Biological Psychology Flashcards
Amygala
Part of brain for emotions
Autonomic nervous system (ANS)
Something you don’t think about
-heartbeat breathing lungs
Axon
Cable that sends messages from one neuron to another
Binding problem
Mystery on why all the parts of the brain work together.
Cell body
Neuron that contains the nucleus of the cell
Action potential
When a neuron fired at -70 milo volts
Central nervous system
Brain and spinal cord
Cerebellum
Brain area primary for balance
Corpus callousness
Tissues that connects the 2 brain hemispheres
Dendrite
Branches structures of neurons that receives transmissions from other neurons
Dopamine
Neurotransmitter that controls movement
Electroencephalograph
Measures brain activity
Endocrine system
Contains the glands which manufacture hormones
Endorphins
Natural pain killers
Epilepsy
Seizures caused by abnormal brain activity
Frontal lobe
In charge of planning and higher order thinking
Functional magnetic resonance imaging (fMRI)
Measures amount of hemoglobin a in different parts of the brain
Glial
Cell that insulated, provides nourishment and removes waste.
Hemisphere
Either the left or right side of the brain
Hypothalamus
Brain area responsible for appetite
Magnetoencephalograph
Measures magnetic changes during brain activity
Medulla
Controls vital functions of brain
Breathing, heart
Mirror neurons
Copy cat neurons
Myelin sheath
Coat around the axon that speeds of transmission of impulse
Neurons
Cell in nervous system that receives information and transmits it to other neurons
Neurotransmitters
Chemical messengers found in the terminal of an axon
Occipital lobe
Critical for vision
Parasympathetic nervous system
Calms you down
Parietal lobe
Sense of touch
Parkinson’s disease
Difficult in movement, rigidity, depressed mood, low on dopamine
Positron emission tomography (pet)
Image of brain activity by radioactivity emitted from injected chemicals
Plasticity
Brains ability to repair itself
Pons
Controls muscles in the head
Post synaptic neuron
Receiving end of a synapses
Prefrontal cortex
Tissue that plans movement & certain aspects of memory
Presynaptic neuron (terminal bouton)
Sends/releases neurotransmitter into the synapse
Hormone
Chemical made by glands -carried by blood
Primary motor cortex
Controls fine movement
Primary somatosensory cortex
Received touch sensations
Resting potential
Build up before fire
Stem cells
Undifferentiated cells
Sympathetic nervous system
Fight or flight
Synapse
Gap between neurons
Temporal lobe
Hearing
Ablation
Surgical removal of tissues
Acetylcholine
Activates muscles
Adrenal glands
Stress
Face Agnosis
Can’t remember familiar faces
Aphasia
Disturbance resulting from brain damage
Association cortex
all areas not primarily sensory or motor in function
Broca’s area
Enables speak
Cranial nerves
Nerves that don’t go through spinal cord
Dominant hemisphere
Side of preference
Epinephrine
Fear, adrenaline, arouse
Human growth hormone
Gland that promotes bodily growth
Hippopotamus
Storing memories
Lateralization
Each hemisphere has a certain job
Lambic system
Nervous system linked with emotional response
Melatonin
Hormone released by pineal gland for biorhythms
Lock and key
Chemical in your body has a place
Vesicles
Vessel that neurotransmitters float across the synapse in
Nerve
Bundle of axons
