  1. Interdisciplinary field studying how biological processes relate to behavioral and mental processes
    Neuroscience
  2. Cells responsible for receiving and transmitting electrochemical information
    Neurons
  3. Comprises the brain and the nerves that extend throughout the body
    Nervous system
  4. Receives info from other neurons & sensory receptors
    Dendrites
  5. Receives info from dendrites
    Cell body
  6. Carries neuron's message to other cell bodies
    Axon
  7. Covers axon to insulate and speed neural impulses
    Myelin sheath
  8. Forms junctions with other cells and release chemicals called neurotransmitters
    Terminal buttons of axon
  9. A neural impulse that carries information along the axon of a neuron
    Action potential
  10. Between neurons, communication occurs through transmission of neural information across a...
    Synapse
  11. Chemicals released by neurons that alter activity in other neurons
    Neurotransmitters
  12. When neurotransmitters in the synapse are reabsorbed into the sending neurons
    Reuptake
  13. Name some key neurotransmitters
    Serotonin, Acetylcholine, Domapine, Norepinephrine, Epinephrine, GABA
  14. Collection of glands that manufacture and secrete hormones into the bloodstream
    Endocrine system
  15. Consists of the brain and spinal cord
    Central Nervous System
  16. Consists of all nerves and neurons connectins CNS to the rest of the body
    Peripheral Nervous System
  17. Brain's lifelong ability to reorganize and change its structure and function throughout the life span
    Neuroplasticity
  18. Process by which new neurons are generated
    Neurogenesis
  19. Immature cells with the potential to develop into almost any type of cell
    Stem Cells
  20. Transmits information into and out of brain
    Spinal Cord
  21. Connects to sensory receptors and controls skeletal muscles
    Somatic NS
  22. Controls involuntary bodily functions and is further subdivided into Sympathetic and Parasympathetic NS
    Autonomic NS
  23. This NS is responsible for arousal
    Sympathetic
  24. This NS is responsible for calming
    Parasympathetic
  25. Involved with life survival functions
    Medulla
  26. Involved with respiration, movement, waking, sleeping, and dreaming
    Pons
  27. Involved with coordination of muscular movement, balance
    Cerebellum
  28. Runs through the hindbrain, midbrain, and brainstem; screens incoming information and controls arousal
    Reticular Formation
  29. Relays sensory messages to the cerebral cortex
    Thalamus
  30. Responsible for drives, hormones, and regulating the body's internal environment
    Hypothalamus
  31. Interconnected group of forebrain structure involved with emotions, drives, & memory
    Limbic System
  32. Part of the lymbic system involved with emotions
    Amygdala
  33. Involved with formation of new memories
    Hippocampus
  34. Regulatory system inthe limbic system
    Hypothalamus
  35. Controlled by the brain and secretes hormones taken into the bloodstream
    Pituitary Gland
  36. Thin surface layer on the left and right cerebral hemispheres; regulates complex behavior
    Cerebral Cortex
  37. Receives and coordinates messages from other lobes responsible for motor control, speech production, thinking, personality, emotion, and memory
    Frontal lobe
  38. Located at the top of the brain directly behind the frontal lobes; responsible for interpreting bodily sensations
    Parietal lobe
  39. Located on each side of the brain above the ears; responsible for audition, language comprehension, memory and some emotional control
    Temporal lobe
  40. Located at the back of the brain; responsible for vision and visual perception
    Occipital lobe
  41. Provides information on the role and functions of the left & right hemispheres
    Corpus callosum
  42. Describes how the left & right hemispheres of the brain specialize in particular (often overlapping) operations
    Lateralization
  43. The brain's ability to modify itself after some type of injury or illness
    Plasticity
  44. Experimentally destroys or removes brain tissue to study animal behaviors after such destruction
    Lesion
  45. Amplified recording of the electrical waves sweeping across the brain's surface, measured by electrodes
    Electroencephalogram (EEG)
  46. Scans a visual display of brain activity that detects a radioactive form of glucose while the brain performs a given task
    PET Scan
  47. Uses magnetic fields and radio waves to produce computer-generated images that distinguish among diff types of brain tissue.
    MRI Scan
