Here's a question we can all appreciate - do you (anyone) think that the information in short term memory is <i>actually</i> represented in prefrontal cortex, or is the PFC more of a switching board that keeps different areas of the brain constantly active? For instance, the Baddeley & Hitch...
Has anyone else noticed that the cortex processes information from the foot suspiciously close to the genitalia? Maybe we can finally understand that godawful foot fetish! Cross wiring of some sort ;)
The nerves in your body, generally, branch out directly from the spinal cord. When a nerve is stimulated by touch, the signal travels to the spinal cord, up the spinal cord, and into the brainstem. The pathways reach the thalamus, which is a sort of switching station in the brain, at the top...
Most of us are pretty certain why we feel good or bad - the question was why the memory of a feeling elicits that same feeling. Even within the confines of your conveniently vague response, jiohdi, I must point out that no expectations or boundaries are exceeded or violated by the act of...
Let me narrow this question down a little, if I may: How are specific memories tagged with emotion? Let's take fear, because that's what I've been looking at recently (and broadly) : The lateral nucleus of the amygdala supposedly pairs stimuli (using run of the mill hebbian interaction) in...
I've always been fascinated with split-brain patients. You know early on, before these studies (because they seem to function fairly well otherwise) scientists used to joke that the only two things the corpus collosum was good for was holding the hemispheres together and propogating seizures...
What Mk is talking about is working memory. You can find stories on this in Scientific American and other such publications. A few of these stories centered around chess grandmasters. The idea is this: you can only keep track of six or seven things at once. This is where the five plus or...
Hey, if you remember the source of that research, or if you come across anymore - let me know. I'm really starting to get interested in neuroscience and molecular bio.
Ah - right to the heart of the issue. After the initial "shock" of discontinuing my meds, I noticed a number of things that concerned me. The first was that I was emotionally volatile - I had no way of predicting my mood. That prompted me to research the drug a little (Trileptal), and I found...
Incredible - my disorder also began with a fall (at seven), but I'm unsure if the fall was the cause or if the seizure caused the fall. I had a number of small concussions as a younger child as well but we tend to believe that partial seizures were to blame in some of those instances - this is...
Wow - I can't believe no one has answered you. Though I'm not at all qualified to speak of diagnosis, I did have a non-epileptic seizure disorder growing up, and I've undergone a number of CT Scans. But from what I've gathered, they aren't looking for direct evidence for epilepsy - instead...
Also keep in mind that appendages may evolve for one purpose but are then used for another. I know little about marine evolution, but it's possible. For instance, there's a theory that feathers started out as an alternative to hair, used to regulate body temperature, and only later became...
Ahh - I recall something similar to this from a while back - patterns in the olfactory bulb. I hadn't been able to come up with a suitable absraction for an efferent pattern. I must admit it's a hell of a lot more attractive than a some unbelievably complicated schematic of individual...
