Chapter 3/neuroscience and behavior

Communication in the nervous system/ Why psychologists are concerned with human biology?

Nervous tissue/basics

Neural impulse/using energy to communicate information

Describe the structure of the neuron, including the major parts such as the dendrites, axon, and terminal buttons.  Describe how neural impulses are generated.  Distinguish between resting and action potentials.

Types of neurons

sensory/receive input from external world

motor/send impulses out from brain

interneurons/conduct impulses between neurons

Neurotransmitters and behavior/part of electrochemical process

Describe how nerve cells communicate (across the synaptic membrane).  Describe the impact of neurotransmitter substances and drugs on human behavior.

 

Organization of the nervous system

Peripheral nervous system/autonomic (sympathetic and parasympathetic) and somatic nervous systems/identify functions of each nervous system

Central nervous system/brain (voluntary) and spinal cord (involuntary/reflexive behavior)

 

Research methods/studying the brain

EEG/neural activity (brain waves)

CAT scan

PET scan

MRI

Lesioning/behavioral affects (changes in human behavior)

 

Brain and behavior

Hindbrain

Medulla

Pons

Cerebellum

Midbrain

reticular formation

Forebrain/

thalamus/

hypothalamus

limbic system

hippocampus

septal area

cerebral cortex (highest level of functioning provides human distinctiveness-four lobes/description of the sensory and motor functions of the cerebral cortex

plasticity of brain/compensatory structure

 

 

right brain/left brain-cerebral laterality

split brain research (Sperry)/bisecting the brain

hemispheric specialization/intact brain (right/left brain dominance)

 

Endocrine system/another method of communication/release hormones directly into the blood stream for immediacy of action as opposed to exocrine glandular system (tear ducts) that secret hormones indirectly

Pituitary gland

Adrenal gland

Sexual glands

 

Heredity and behavior/ Is it the genes?

Basic principles of genetics

Research methods/studying hereditary influence (human genome project)

Interplay of nature/nurture (heredity/environment)/which factor is more significant?  Is it an interaction effect?  What are the implications for human behavior?  What are the implications for selective breeding, especially among human beings?  Can we breed the “perfect” species?

 

Evolutionary bases of behavior

Role of Darwin’s insights

Refinements to evolutionary theory

Behaviors as adaptive traits (physical/psychological)

Parental influences/mating behavior
