FYI: We try to leave jargon out of our videos, but if you want to learn more about this topic, here are some handy keywords to get your googling started:
Brain lesion: Damage to the brain caused by disease or injury.
Broca’s area: Region in the frontal lobe associated with speech production.
Fusiform face area: Structure near the back of the brain associated with facial recognition.
Hippocampus: Seahorse-shaped brain structure associated with memory formation.
Amygdala: Small brain structure associated with emotions and memories.
fMRI: An imaging procedure that measures brain activity by tracking changes associated with blood flow.

I work with brains. More specifically, I work with specialized immune-type cells that are native to the brain and what happens to them when the brain is developing under certain stressors. I actually do say..."there's still brain on that..." because it's all part of the job. That gave me a laugh.

@foobargorch 7 жыл бұрын

There's also the complementary idea, namely what kind of behaviour/activity/brain function is really something that is one thing, that exists in a module. This video is great context for understanding the concept of dissociation and double dissociation, which is used to map out that territory. There's a great paper, "Memory, Perception, and the Ventral Visual-Perirhinal-Hippocampal Stream: Thinking Outside of the Boxes", by Bussey & Saksida, 2007. It really made me think hard about the difference in how we talk about the things the brain does, and how much our day to day thinking colours the kinds of questions that we ask. Highly reccomended!

What happens when the optic chiasma is severed? Can traffic be re-directed through the corpus callosum?

@Ancor3 7 жыл бұрын

If you're talking about visual information, it doesn't look like it can. Damage to the optic chiasm results in a specific type of visual field deficit depending on which nerves were severed. This wouldn't happen if visual information had the alternative route of the corpus callosum. www.ncbi.nlm.nih.gov/books/NBK10912/

i do know that certain types of blindness makes the brain rewire which allows blind people to tell at 80% accuracy where the source of light was coming from, but they where not able to see anything consciously.

@darkenergylambda 7 жыл бұрын

I can answer that! If it is completely severed you are 100% blind. But if the central regions are effected you get bitemporal hemiopisa - that is you loose your peripheral vision. Central vision fibers travel through the lateral portions of the chiasma whereas peripheral travel through the central regions. As for re-direction, that will not happen as there are no other connections to the optic nerve.

None of them. The midbrain and diencephalon help integrate the senses with higher cognitive function. And fasiculi connect different regions of the brains. But none of them "know" what areas of the brain do what, they just do what they've evolved to do.
