Document Summary

Week 5: hm & the anatomy and function of the temporal lobes. Hm: most studied man in neuroscience, had severe temporal lobe epilepsy. Epilepsy: neurons pass on information by firing and causing the next neuron to fire. Intermittent: not permanent, biochemical basis of seizures, 2 types of synapse, excitatory (glutamate) increases speed of excitation. Inhibitory (gamma-amino-butyric acid gaba) increases nervous system stability (slows down: combination of these 2 is what causes neurons to fire, so all neurons start firing together. In a seizure, there is a reduction in gaba: no inhibitory release to calm this down, group excitation seizure. Memory types: types of amnesia, retrograde amnesia: Impairment for memories created prior to injury: anterograde amnesia: Impairment in learning novel information: types of memory, declarative, memory of facts and events, memories that can be consciously recalled ( declared", procedural, unconscious memory of skills and how to do things, e. g. tying a shoelace, riding a bike.
