psy 2400: behavioral neuroscience exam 1

Mind:

a special purpose machine that uses information to construct the present and to predict the future.

Cognitive closure:

cant understand stuff because your embodied in that question

Dualism:

body and soul are two separate things

Monoism (physicalism)

your nervous system is you. Everything is deterministic

Emergence:

a physical thing has a function and concept which makes it its self, but when those are taken away its not that thing anymore

Epigenetics:

the study of heritable changes in gene function that occur without altering the underlying DNA sequence

Neuron doctrine

The brain is composed of neurons and other cells that are structurally, functionally, and metabolically independent, and send signals through electrical impules

Dendrites

branches on a neuron that recieves info from other cells

Synapse

gap between cells where info is transferred through

Cell body

where info is processed 

Axon Pillar

where the action potential is formed

Axon

where info is passed through the neuron

Axon terminals

where info is sent out to other neurons and encoded.

Glial Cells

Nonneuronal brain cells that provide structural, nutritional, and other types of support to the brain. 

Astrocytes

filter/regulators of neurons

types of glial cells

astrocytes, microglial, oligodendrocytes, schwann

Microglial cells:

Migrate to areas of injury and Remove debris from injured/dead cells

Oligodendrocytes (CNS) and Schwann Cells (PNS)

Form myelin sheath, insulates axons

CT scan

xray source moved in arc around head

PET scan

measures glucose in part of the brain (inferring high vs low brain activity)

FMRI

measures oxyhemoglobin vs deoxyhemoglobin in part of brain to measure activity
