BIOLOGICAL FOUNDATIONS of BEHAVIOR-Part 1
Transcript of BIOLOGICAL FOUNDATIONS of BEHAVIOR-Part 1
The capacity of our
brains to change in
NEUROGENESIS - The production
of new brain cells.
*ACETYLCHOLINE- Excitatory- Movement, Autonomic, Learning, and Memory
*GABA-Inhibitory- in the Central Nervous System, Moods
*GLUTAMATE-Excitatory-in the Central Nervous System- Learning & Memory
*NOREPINEPHERINE-Excitatory-Arousal, Vigilance, and Mood
*DOPAMINE- Excitatory-Motivation, Reward, Planning of Behavior
*SEROTONIN- Inhibitory- Mood, Appetite, Sleep
*ENDORPHINS-Natural Opiates- (Neuropeptide)
*OXYTOCIN -hormone and neurotransmitter- experience of love and bonding
The microscopic space between
two neurons, over which messages pass is called a synapse.
Importance of Neuropeptides
They regulate the activity of other neurons. Key neuropeptides are enkephalins which relieve pain & stress; and, endorphins which induce feelings of pleasure or euphoria.
Threshold - The trigger point for firing neurons...from resting potential (negative charge => action potential (positive charge.
Neuron - An individual nerve cell.

Dendrites, Axon, Axon
BIO-PSYCHOLOGY - THE STUDY OF HOW BIOLOGICAL PROCESSES, ESPECIALLY THOSE OCCURRING IN THE NERVOUS SYSTEM, RELATE TO BEHAVIOR.
2 SUBSYSTEMS OF THE
CENTRAL (CNS) :
Brain & Spinal Cord
PERIPHERAL: Network that carries information to and from the CNS
PART 1 - Biological Foundations of Behavior
Monkey See, Monkey Do....Mirror Neurons are neurons that become active when a motor action is carried out and when another organism is observed carrying out the same action. They are important for social understanding...? Autism?
