It’s hard to google this, a lot of it gets piled under diet advice, or advice for parents with autistic children.
I haven’t been able to find anyyy info about adults with trauma who use food to calm the nervous system and who seem to be seeking particular sensory input.
I noticed recently that I reach for chewy foods when I need to chill out from flight, and reach for crunchy foods when I need to get out of freeze. Besides blowing my mind, I have no idea where to go with this. Is there other ways to meet the sensory need without eating? Another way to bring myself back to the parasympathetic system? Are there any books or resources on this?
Hi! Long story short I'm a first year trying to figure out what specialization I want to go into, and SMS sounds really cool to me! However the program does have a lot of elective space and I'm having a hard time visualizing what the courseload would look like for me in second, third, or fourth year. I'm just not sure how "21-36 units of electives" spreads out across your degree and stuff like that. There seems to be some required second year courses, but I know you don't have to take all of them in second year necessarily, etc. so that's why I'm struggling a bit to understand the academic calendar and how students in SMS usually choose to spread everything out.
If you're in SMS, I would love it and it would help me out a ton if you could please share what courses you took each year (mainly interested in second year!) and what you thought of them. Thank you!!
Direct implications for anyone who developed VSS symptoms after marijuana use. It is the THC rather than CBD. Before getting sick I was never an abuser of medications (whether prescription or OTC) or recreational drugs at all. I have only used marijuana twice in my entire life - once at 17 or 18 as a senior in high school and the other very briefly (like one or two puffs) at 21. Both times I got VS immediately (within minutes to an hour) after which lasted until roughly around 24 - 36 hours afterward. Before and since then (until the medication in December) I never had even a single iota of a trace even .01% of any VS/VSS symptoms even remotely for 29 years of life. The exact same swirl of colors (purple, green, and turquoise) preceded it which I ignorantly and mistakenly just attributed to its purported properties as a possible hallucinogen in some people without considering the broader implications.
That exact pattern and trajectory of events, from the dimming and darkened vision down to even the exact same swirl of colors down to the letter was replicated when I took an anticholinergic medication which dampened activity of cholinergic neurons in the same part of the brainstem controlling thalamic activity by way of receptor antagonism (though of course I did not do this intentionally and things went awry for specific reasons which are another story).
It is spelled out quite plainly and succinctly here:
> Cannabinoids and the cholinergic system
> delta 9-Tetrahydrocannabinol (THC) decreases EEG activation and causes slow waves in the cat. The EEG slow-wave activity is accompanied by a concomitant decrease in acetylcholine release from the neocortex. The findings suggest that THC depresses the brain stem activating system. Large doses of delta 8- and delta 9-THC increase brain acetylcholine levels in rodents such as the mouse and rat, but this effect is not seen with minimal doses of the cannabinoids which show behavioral effects. The most dramatic change produced by THC is that brain acetylcholine utilization is reduced primarily in the hippocampus.

Ascending reticular activating system (ARAS) is, again, the sensory gate.
> The reticular activating system is a short, pencil-sized piece of the brain located just above where the spinal cord is attached to the brain. It acts as the gatekeeper of information between most sensory systems and the conscious mind.

... keep reading on reddit ➡Hi everyone! I'm a first year life sci (like so many other people on this subreddit LOL) who just got my CHEM 1A03 mark back, and am now trying to think about specializations based on what is realistically in my reach after how I did in the two courses I have marks back for (PSYCH 1X03 and CHEM 1A03) while I anticipate others.
I'm currently debating between Honours Life Science (for elective space and freedom to structure my degree, maybe with a minor in psychology!) and Sensory Motor Systems (which sounds like a good blend of my interests in physiology/kinesiology, neuroscience, etc. while still giving a good amount of elective space) I definitely hear less about the SMS spec though.
To anyone in either of these specializations, would you mind answering a few of these questions and/or letting me shoot you a PM to discuss?
- How did you find the workload going from first year to second? How is the workload in general in either of these programs?
- How's the elective space? I've already checked this out on the academic calendar for both programs but I'm not sure how this translates to year-per-year # of electives.
- How realistic is it to keep a high GPA in Honours Life Science vs. SMS? I'm aiming for professional school so I'd definitely like a specialization where I can take some lighter courses that are more focused around my interests as opposed to the really broad, intensive courses I've had in first year so far. I've done better so far this year in courses that interested me and I'd like to take more of them. I'm not sure whether Honours Life Science or specializing in SMS is a better choice for me.
- What are the drawbacks of specializing? What are the drawbacks of not specializing? I'm trying to make sure I make a well informed, realistic choice.
- What is the grade cutoff for SMS?
Thank you so much!! Hope everyone has a wonderful restful winter break, you've all earned it :'))
do any upper years know what the cut-off has been for this spec in the past years? ive been told it's not that competitive but there aren't that many people in the program so i'm still a bit worried about my chances
i'm doing very poorly in chem right now and its going to completely ruin my gpa this sem so i feel like i'm not going to get in lol. would the cut-off be around 8-9? or is it more competitive than that
I'll explain in comments lol
I'm looking at this graph explaining how the density of the rods and cones differ depending how many degrees it deviates away from from the fovea.
question 1: the x axis is titled "Eccentricity (degrees)" where the Fovea is in the middle at 0 degrees and each side extends to 80 degrees. The right end of the x axis is titled "Nasal" and the left end is titled "Temporal".
Does "Nasal" just refer to the deviation towards the nose (so the left eye towards the right and the right eye towards the left) and "Temporal" referring to the opposite direction (so the left eye towards the left and the right eye towards the right)?
what I don't understand is the use of the word "Temporal". I thought temporal refers to something related to time.
Question 2: there is a vertical graph from around x=10 to x=20 degrees on the "Nasal" side represented as the blind spot, but why does this not exist on the "Temporal" side of x=10 to x=20?
I'm sorry that my questions might be difficult to understand. I would love to post the graph, but I can't do that on this sub so it's really difficult to explain my question. If you guys know any alternative subreddit where I can ask a question and post an image as a reference please let me know.
Perhaps a bit of a rant... but does anyone else feel like most processes / systems in society bias towards a sensory way of processing information? Being an INFJ, I often feel like I need to "translate" my Ni-led thoughts to be more sensory (detail orientated, procedural, etc.). Communicating in a more sensory way has basically become a second language for me, one which always remains a bit strenuous. I suspect most intuitive-dominant people learn to "speak" sensory out of necessity, due to the predominance of sensory types. Is it fair to say that the sensory way of processing information and communicating is effectively the lingua franca of most organizations? Or, am I just being grumpy?...

The Mechanical Basis of Memory – the MeshCODE Theory
- School of Biosciences, University of Kent, Canterbury, United Kingdom
One of the major unsolved mysteries of biological science concerns the question of where and in what form information is stored in the brain. I propose that memory is stored in the brain in a mechanically encoded binary format written into the conformations of proteins found in the cell-extracellular matrix (ECM) adhesions that organise each and every synapse. The MeshCODE framework outlined here represents a unifying theory of data storage in animals, providing read-write storage of both dynamic and persistent information in a binary format. Mechanosensitive proteins that contain force-dependent switches can store information persistently, which can be written or updated using small changes in mechanical force. These mechanosensitive proteins, such as talin, scaffold each synapse, creating a meshwork of switches that together form a code, the so-called MeshCODE. Large signalling complexes assemble on these scaffolds as a function of the switch patterns and these complexes would both stabilise the patterns and coordinate synaptic regulators to dynamically tune synaptic activity. Synaptic transmission and action potential spike trains would operate the cytoskeletal machinery to write and update the synaptic MeshCODEs, thereby propagating this coding throughout the organism. Based on established biophysical principles, such a mechanical basis for memory would provide a physical location for data storage in the brain, with the binary patterns, encoded in the information-storing mechanosensitive molecules in the synaptic scaffolds, and the complexes that form on them, representing the physical location of engrams. Furthermore, the conversion and storage of sensory and temporal inputs into a binary format would constitute an addressable read-write memory system, supporting the view of the mind as an organic supercomputer.
Im in love with the idea of this program. All the pre-reqs are right up my ally. I know it's a newer program, so I cant really find anything about it. If you or if you know anyone in this program please pm me! id love to know about the experience.
Im interested in biology, psychology, neuroscience and medicine.
Im deciding between this and biology with a minor in psych.
The room of electives in this program makes me drool. And the applied placement classes! wow!!
I’d like a bit of insight into these programs but I’m not really sure where to get more info, cuz I kinda wanna hear it first hand. If you’re in it, did you enjoy it/ what can you expect in terms of courses?
I'm just confused about what last year's cut-off range was because I can't seem to find it. I already know that it is limited enrolment and about 25-30 ppl get in. Any ppl from upper-years or anyone that has any info ab this program would be appreciated.
I’m thinking of having this as my top choice to specialize in, but I just wanted to get some input from anyone who might be in the program right now, on what its like? And also, what do you plan on doing after graduating from this program?
According to this paper: https://psycnet.apa.org/record/2009-04583-006
The endogenous opioid system plays a role in sensory gating, it further demonstrates that administration of an opioid receptor agonist produces an improvement in those measures.
Could chronic administration of an opioid antagonist like naltrexone cause deficits in sensory gating? Would these changes be reversible?
I find myself getting distracted a lot ever since I have been taking naltrexone, could this be because of the above mentioned effects?
Do I process more then someone who can have their brain filter better? Or the other way around?
Does this correspond with quickness to overwhelm or sensory sensitivity being heightened or decreased?
Does this lead to an increase or decrease in puzzle solving or pattern finding skills?
How would this effect abilities in hyperfocus?
I appreciate the help on this. Thanks.
So I failed the chem 1aa3 exam and ended up with a D in the course. And now, from what I’m calculating, I’ll probably have a final GPA of 8.5 ish for both terms combined. I was wondering if anyone knows what the previous GPA cutoff for sensory motor systems was and do you think I have a chance at getting in with a 8?
How were these classes?
