- A network of neurons involved in regulating attention, alertness, and arousal
- reticular formation
- A set of structures in the brain especially involved in the experience of emotion
- Limbic system
- lobes at the back of the head that process visual stimuli
- occipital lobes
- part of the hindbrain involved in regulating vital life functions
- medulla
- lobes at the top and front of the brain, most involved in higher-order functions
- frontal lobes
- portion of the forebrain divided into two hemispheres
- cerebrum
- part of the limbic system most involved in the formation of memories
- hippocampus
- brain structure in the limbic system involved in many functions, including sexual reproduction, emotional reactions, and maintaining internal body temperature
- hypothalamus
- lobes located in the upper back of the head; process information relation to touch, pressure, external temperature
- parietal lobes
- one component of the limbic system; particularly involved in the experiences of fear, agression
- amygdala
- lobes located on the sides of the head near the ear; primary function involves processing speech/sound
- temporal lobes
- outer covering of the cerebrum
- cerebral cortex
- brain structure located in the back of the head; vital for balance and coordination
- cerebellum
- the part of the brain that joins the cerebral hemispheres
- corpus callosum
- the amygdala, hippocampus, and parts of the thalamus and hypothalamus make up the...
- limbic system
- which lobe of the brain is responsbile for hearing
- temporal
- what makes up 80% of the brain's total mass?
- cerebral cortex
- brain chemicals that moderate pain messages and produce feelings of pleasure
- endorphins
- nerve cells
- neurons
- fibers extending out from the soma of the neuron; receive incoming messages from adjoining neurons
- dendrite
- neurons in the peripheral nervous system that transport messages from spinal cord to muscles and glands
- motor neurons
- connection between neurons where neural message becomes chemical (carried by neurotransmitters)
- synapse
- chemicals present in the brain that allow for message transmissions among nerve cells
- neurotransmitters
- The part of the neuron conducting messages down the length of the cell toward connections with other neurons; usually the longest part of a neuron
- axon
- a fatty protective layer that covers the axons of some nerve cells and helps speed transmission of neural impulses
- myelin sheath
- neurons that receive messages from sensory receptors and transmit that information to the spinal cord
- sensory neurons
- locations on neurons receiving incoming messages; neurotransmitters fit into these sites
- receptor site
- the part of the neuron that receives incoming messages is the...
- dendrites
- axons are often covered with a layer called the ___ that contain(s) the nodes of ranvier
- myelin sheath
- transmission of a neural impulse travels from ___ at the receiving end of the cell to ___ at the other end of the cell
- dendrites; terminal buttons
- neural messages become chemical in nature and are transmitted by neurotransmitters across the...
- synapse
- ___ carry messages away from the spinal cord and brain
- motor neurons
- adopted by Wundt, analysis of the basic elements that constitute the mind
- Structuralism
- functionalism
- developed by William James, study of the purpose mental processes serve in enabling people to adapt to their enviroment
- hindbrain
- area of the brain that coordinates info in and out of the spinal cord
- medulla
- extension of the spinal cord into the skull that coordinates heart rate, circulation, and respiration]
- Cerebellum
- structure of hindbrain that controls fine motor skills
- pons
- brain structure that relays information from the cerebellum to the rest of the brain
- subcortical structure that transmits information to
- Thalamus
- Occipital Lobe
- region of cerebral cortex that processes visual information
- parietal lobe
- region of cerebral cortex processes information about touch
- region of cerebral cortex responsible for hearing
- Temporal Lobe
- frontal lobe
- region of cerebral cortex that has specialized areas for movement, abstract thinking, planning, memory and judgement
- hippocampus
- structure critical for creating new memories
- area of neurons running down the front of the parietal lobes responsible for processing information from the skin and internal body receptors for touch, temperature, body position, and possibly taste
- Somatosensory cortex
- highest level of the brain, critical for complex cognitive, emotional, sensory and motor functions, contains the cerebral cortex and its subcortical structures
- forebrain
- coordinates information coming out of the spinal cord and controls the basic functions of life, contains the medulla, reticular formation, the cerebellum, and the pons
- hindbrain
- Peripheral NS?
- sensory systems and skeletal motor systems
- Autonomic NS?
- parasympathetic NS and sympathetic NS
- action potential
- exitation traveling across an axon at a constant strength, no matter the distance.
- resting potential
- an electrical polarization across the membrane of an axon.
- presynaptic neuron
- message sending
- postsynaptic neuron
- message recieving
- graded potentials
- ripples in pond; electrochemical changes are greatest near synapses. get weaker the farther away.
