Brain Stuff I
The brain makes sense of random neural activity that spreads upward from the brainstem during sleep.
What is neural static?
Name the 2 parts of the autonomic nervous system.
What is the parasympathetic and sympathetic?
This regulates physical processes and influence behavior
What is the endocrine system?
It acts as a filter that relays important information to other brain areas
What is reticular formation?
This occurs during which the neuron is unable to fire or unable to respond to any stimulation
What is the refractory period?
The brain’s ability to change by reorganizing after damage or building new pathways based on experience
What is Cognitive Psychology?
It Controls the body’s skeletal muscles
What is the somatic nervous system?
The brain’s natural mode of information processing for many functions
What is parallel processing?
An injury could cause the loss of sensation and voluntary movement.
What is the spinal cord?
Are brain cells that fire when you do an action, and also when you simply watch someone else doing the same action.
What are Mirror Neurons?
Is different from unconsciousness caused due to coma, general anesthesia, or hibernation
What is sleep?
It includes the amygdala, hypothalamus, and hippocampus
What is the limbic system?
The brain’s ability to change by reorganizing after damage or building new pathways based on experience
What is plasticity?
It was discovered by Fritsch and Hitzig.
What is the motor cortex?
A brief change in electrical voltage that occurs between the inside and outside of an axon when a neuron is stimulated.
What is the action potential?
The scientific study of the links between biological and psychological processes.
What is Biological Psychology?
This Controls the glands and muscles of internal organs
What is the autonomic nervous system?
This reveals blood flow and, therefore, brain activity.
What is functional MRI (fMRI)?
This helps coordinate movement and control sleep
What is the pons?
Name the 3 parts of a neuron.
What are the cell body, axons & dendrites?
A large band of neural fibers connecting both brain hemispheres and carrying messages between them
What is the corpus callosum?
Chemical messengers manufactured by the endocrine glands.
What are hormones?
Neuron-produced chemicals that cross the synaptic gap to carry messages to other neurons or muscles
What are neurotransmitters?
It is 2 lima-bean-sized neural clusters that enable aggression and fear and are linked to emotion
What is the amygdala?
They play a vital role in learning, thinking, and memory
What are glial cells/glia?
