Biological Psychology

in charge of communicating in the nervous system via electric charges that release neurotransmitters

collecting information from other neurons, receives communication

centre of the cell, stores genetic information of the cell

the electric charge from axon hillock travels down the _____

takes all messages from soma or dendrites and regulates all the information, averages it and decides what to do

gaps on the axon, further speeds the electric signal/transmission speed

release transmitter, commuting with other neurons through sending information

tiny bumps around the axon, speeds up electric charge travelling down the axon; facilitates repair of the axon if it is damaged

chemicals released by neurons

neurons are specialized cells that ____, ____, and ____ information

neurons are either firing _____ or not

these neurotransmitter can unlock ___ channels, allowing excitatory or inhibitory messages to enter neuron

support neurons and assist in the formation of the myelin sheath

found in the peripheral nervous system

responsible for giving neurons the nourishment they need to function

responsible for cleaning up the debris left from damaged neurons

responsible for voluntary movement/activities, sending and receiving those commands

sending commands to make our heart pump

sensory inputs

responsible for digestion, heart rate, breathing, eye dilation, whether we have to urinate or not

controls facial expressions

facial sensation and jaw movement

the fundamental foundation of the nervous system, and how it works

fluid that runs throughout the brain and takes up the empty space that takes up our skull, cushioning the brain

motor control (fine tuning) and coordination, balance, eye movement, learning and cognitive abilities, very wrinkly = well developed

sleep control, connects brainstem to cerebellum

processing and control of our autonomic activities heart rate, blood pressure, breathing, muscle tone, circulation

general arousal, brain activity when we are awake and active

visual system, attention and with involuntary directing your attention towards visual stimuli

auditory system, attention and with involuntary shift of our entire head towards auditory stimuli (loud noises)

source of the dopamine system- control of voluntary movement

relay station for all sensory information except smell

controls pituitary gland, autonomic nervous system, physiological maintenance (homeostasis)

regulates the endocrine system

emotion and memory

negative emotions (anger, fear, etc.)

memory and spatial ability

communication between cerebral hemispheres

final part of the brain that developed (more wrinkly, the larger it is; more smooth, the smaller it is)

emotion processing, where our personalities are stored, decision making and planning

create the plans to move

planning, strategies, self-awareness, and reasoning

responsible for creation of speech

processing spatial information, figuring out where things are in space

responsible for storing memories, language comprehension

use sight to gather information

processing of smell

first ways to study the brain

stimulating specific areas of the brain with a weak electrical current and observing behaviour

magnetic coil stimulates brain

electroencephalograph monitors averaged electrical activity of the brain over time

measures both electric and magnetic activity

uses x-rays, can detect tumors, lesions, and other abnormalities, cannot see the functions of the brain

brain structure, magnetic fields, uses magnets by pushing around the atoms they are able too

brain function, radioactive chemicals, brightest colours indicate greatest activity

non-evasive, brain structure and function, tracks oxygen flow

substances that contain chemicals like neurotransmitters that affect synapse

excitatory neurotransmitters: dopamine, ____, _____

inhibitory neurotransmitters: _____, serotonin

mass inhibition in the nervous system

mass excitation in the nervous system

mass excitation in specific brain regions related to sensory

cause, facilitate, or stimulate the release of dopamine in stage two

in stage 5, _____ targets dopamine and norepinephrine and cause mass excitation

the neurons natural ability to create a neurotransmitter will be inhibited, nervous system becomes reliant on _____ to be happy

blocking dopamine from being released

targets serotonin, prevents the ability of serotonin to be re-uptake, endlessly bind to the postsynaptic neuron
