1 Biology and Behavior (Kaplan) Flashcards
Franz Gall
Earliest theories regarding behavior, intellect, and personality might be linked to brain anatomy.
- Developed doctrine of phrenology
- Believed you could attribute psychological characteristics based on structure of skull.
Pierre Flourens
First person to study functions of major sections of the brain.
- Via extirpation on pigeons and rabbits.
- assertion that brain had specific parts with specific functions.
William James
-Functionalism: how mental processes hep individuals adapt to their environment
John Dewey
- Important figure in functionalism
- Believed psychology should focus on the study of the organism as a whole as it functioned to adapt to the environment.
Paul Broca
Contributed to physiological studies by observing patients with brain damage
-Linked specific functional impairments correlated w specific brain lesions
Hermann von Hemholtz
Measured speed of nerve impulse
Sir Charles Sherrington
Inferred existence of synapses
Three Kinds of Nerve Cells
Sensory, motor, interneurons
Sensory neurons
Afferent Neurons
-Transmit sensory info from receptors to spinal cord and brain
Motor Nuerons
Efferent Neurons
-Transmit motor info from brain and spinal cord to muscles and glands
Interneurons
- Most abundant
- linked to reflexive behavior
What two components can the nervous system be broken down into?
Central Nervous system and peripheral nervous system
What two components is the peripheral nervous system composed of?
Somatic nervous system and autonomic nervous system
Somatic nervous system
Consist of sensory and motor neurons.
Autonomic nervous system
Sympathetic and parasympathetic
Sympathetic nervous system
Fight or flight
Parasympathetic nervous system
rest and digest
Meningues
thick sheath of connective tissue that covers the brain. Helps protect the brain, anchor to the skull and reabsorb cerebral fluid.
Three layers of meningues
Dura mater, arachnoid mater, pia mater
Where is hindbrain located?
Located where brain meets spinal cord
What does Hindbrain control?
Controls balance, motor coordination, breathing, digestion, sleeping, and waking.
-Vital functioning necessary for survival.
What parts compose of the Hindbrain
Cerebellum, medulla oblongata, reticular formation
Cerebellum
Refined motor movements
Medulla oblongata
Resp for regulating vital functions (breathing)
