Document Summary
Neuroscience 101 lecture hormones (april 12th, 2016) Neural correlates of the lsd experience revealed by multimodal neuroimaging (robin et al. , All functional imaging is subtraction shows incr/decr in activity during experimental vs control/pretest. Occipital love increased activity correlated with visual hallucinations: incr cbf in visual cortex with incr in reported complex visual hallucinations. Some areas more important for reward and others for motor function. Add dopamine to patients (parkinson"s is loss of dopamine) Schizo is excessive dopamine (too high of a dopamine dose) Difficult to find a good normal balance between the two. Hormones alter neural sensitivity to sensory cues and drive wanting: example: puberty heightens sensitivity to certain things; large increase in hormones alters neuronal responses. Novelty being detected : major histocompatibility complex (mhc) Plays key role in vertebrate immune function. Preference for partners with dissimilar mhc (body odor) in humans and mice. Males demonstrate elaborate courtship and mate bonding displays.
