Ch. 1
The scientific study of the biology of behavior
What is biopsychology?
True False: Evolution proceeds in a single line.
What is False?
Nerves that carry motor signals from the central nervous system to the skeletal system.
What are efferent nerves?
This term refers to when the resting potential of a neuron is not at zero.
This part of neuron sends signals to the terminal ends and into another neruon.
What is the axon?
Research that is intended to bring about some benefit to humankind
What is applied research within biopsychology?
The brain has the ability to adapt and change. At a younger age this is much better but as we get older this worsens.
What is neuroplasticity?
Neurons that short with no axon or very short axon that connects other neurons to each other.
What are interneurons?
Negatively or positively charged particles
What are ions?
The parasympathetic and sympathetic nervous systems are derived from this system.
What is the autonomic nervous system?
The division studies neural mechanisms of behavior through direct manipulation and recording of the brain in controlled experiments.
What is Physiological Psychology?
True/False: Human evaluation and genetics interact with eachother.
The meninge that is closest to the. spine and skull
What is the dura mater?
Cells communicate with this.
What is a neurotransmitter?
This complex structure on the dorsal side of the brain coordinates movement, balance, and posture.
What is the cerebellum?
This division is similar to physiological psychology with an emphasis on how drugs will manipulate the neural activity and behavior of a subject.
What is Psychopharmacology?
Viewing issues or situations as one extreme or another, with no middle ground.
What is dichotomous thinking?
The structure that is responsible for activating systems and keeping the cerebral cortex alert and excitable by sending impulses to it.
What is the reticular formation?
When cells move from -70 mv to -72 mv.
What is a hyperpolarized cell.
This occurs after the threshold of excitement (when the sum of the depolarization or hyperpolarization reaches the axon’s initial segment at any point to depolarize the membrane).
What is an action potential?
This division studies the neural basis of cognition (higher intellectual processes such as thought, memory, attention, etc.)
What Cognitive Neuroscience?
This specific diagnosis allowed us to understand how we can converge the six divisions and use the strengths and weaknesses of each to better understand the brain.
What is Korsakoff's Syndrome?
The structure within the limbic system helps to regulate vital bodily functions like body temperature, hunger, thirst, sleep/wake cycles, and sexual arousal.
What is the hypothalamus?
This monoamine neurotransmitter helps regulate mood, sleep, digestion, and sexual arousal.
What is serotonin?
This amino acid neurotransmitter is derived from Glutamate and helps to calm and relax the nervous system.
What is GABA?
