PSY 3128 Lecture Notes - Lecture 4: Cochlea, Spectrogram, Olfaction
Document Summary
Outline: the nervous system, basics, aging, sensations and perceptions. Neurons and synapses: soma: is the body of the cell, dendrites: receive messages, axons: send messages, synapse: is where axon and dendrites meet. White and gray matter: gray matter: in the brain and spinal cord is made up of cell bodies, white matter: is made up of nerve fibers forming tracts. **starting to do multiple techniques at the same time. Structural changes with age: lower volumes of grey matter resulting from reduced synaptic densities, some regions are more affect than others, e. g. **lower grey matter amounts, could be due to inactive synapses. **reduction in synaptic density, first generation of work is getting a lot of attention. Patient hm, removed circled parts in picture 2 memory impaired. Volume changes by regions: the gradual decline in the volume in the part of the brain.
