The Brain & Imaging
This part of the brain controls balance and coordination
The cerebellum!
The part of the neuron that receives signals
Dendrites
The spinal cord and brain make up this system
Central Nervouse System (CNS)
The process of detecting physical energy from the environment
Sensation
These photoreceptors detect color and work best in bright light
Cones
This structure connects the two hemispheres of the brain
Corpus Callosum
Axon
Nerves outside the CNS go with what system?
Peripheral Nervouse System (PNS)
The process of organizing and interpreting sensory input
Perception
These photoreceptors detect light and dark and help with night vision.
Rods
This type of imaging uses X-rays to show what brain structure?
CT Scan
The space between two neurons where nuerotransmitters are released
Synapse
This part of the nervous system controls voluntary movement.
Somatic Nervouse System
The minimum difference needed to detect a change in stimuli
Difference Threshold.
Have a life cycle of ten days to two weeks
Taste Buds
This type of imaging shows brain activity by tracking blood flow
fMRI
The event that occurs when a nueron fires an electrical signal
Action Potential
"Fight or Flight" or “rest and digest" describe what two divisions.
Sympathetic and Parasympathetic
Perception included what type of processing
Bottom up and top down processing
Snail-shaped structure in the ear that contains the sensory receptor cells of the auditory system.
Cochlea
Damage to this area of the brain can cause a hard time forming new memories.
Hippocampus
The process describes how ions move in and out to create action potential
The movement of sodium and potassium ions.
Sensory neurons carry signals ____ the brain, while motor neurons carry signals ___
to and from
The difference threshold is a constant fraction of the original stimulus -- What Law is this?
Weber's Law
The five main taste sensations
Sweet, sour, salty, biutter and Unami
