Intro & Research
What is the goal of a descriptive study?
Measure a variable. No hypothesized relationships
What parts of the nervous system are part of the CNS?
Brain and spinal cord
What are the two divisions of the somatic nervous system?
Cranial nerves, spinal nerves
What structures are visible from the ventral view of the brain?
Olfactory bulbs, pituitary, brainstem (pons, medulla)
What is the process of generating neurons?
Neurogenesis
What is the goal of an associative study?
Draw correlational relationships between variables. No causal relationships are established.
What are the two divisions of the autonomic nervous system?
Sympathetic, parasympathetic
What kind of cells drive myelination?
Glia
Name the three meninges layers
Dura mater, arachnoid mater, pia mater
Which layers form as cells "pile up" in development?
Ventricular, marginal, and intermediate
What is the goal of an experimental study?
Compare two or more groups on a dependent variable by manipulating the independent variable to systematically understand a causal relationship.
Somatic and Autonomic are part of what division of the nervous system?
Peripheral
What is inside synaptic vesicles, and where are they released from?
Neurotransmitters, terminals
What is the purpose of the choroid plexus?
Make CSF by filtering blood
What purpose do radial glia serve during development?
Migration of neurons
The three methods of studying biopsych (interventions)
Somatic interventions, behavioral interventions, and correlational measures of both together. (give an example for each for practice)
What are the four types of glia?
Myelinating glia (Schwann cells, oligodendrocytes), astrocytes, microglia, radial glia
Differentiate between afferent and efferent nerves
Afferent is AT the brain, Efferent is Exiting or away from the brain
What are the 3 layers present at 18 days?
Ectoderm, mesoderm, endoderm
What is the process of neuron differentiation using signaling molecules?
Induction
What are the five goals of biological psychology?
1. Describing the structure and function of behavior
2. Studying the evolution of behavior
3. Observing the development of behavior over the life span
4. Studying the biological mechanisms of behavior
5. Studying applications of behavioral neuroscience
What are the five aspects of the neuron’s anatomy?
Dendrites, cell body, axon, axon collaterals, axon terminals
How many cranial nerves are there, and what part of the nervous system are they in?
13 total, somatic nervous system
Which layer gives rise to the neural plate, later developing into the nervous system and skin?
Ectoderm
What are the structures present in developing neurons that grow to form synapses?
Growth cones
