Brain and Behavior Flashcards
Franz Gall Theory
Part of the brain responsible for traits will grow as that trait is developed - measured psychological attributes by measuring the skull
Who measured psychological attributes by measuring the skull?
Franz Gall
Pierre Flourens
Observed behavioral consequences of removing various parts of the brain - found that specific parts of the brain have functions and removal of one weakens the whole brain
Who was the first major study of functions of major portions of the brain?
Pierre Flourens
Ablation
Removal of various portions of the brain
William James
Functionalism - system of thought that studied how mental processes help individuals adapt to their environments
Who is considered the father of american psychology?
William James
John Dewey
Believed that organisms react to a stimulus as a whole rather than by the reflex arc (breaks reactions into discrete parts)
Paul Broca
Demonstrated that specific functional impairments are linked to brain lesions
Who examined behavioral deficits in those with brain damage?
Paul Broca
Broca’s area
Portion of the left brain responsible for the motor portion of language
Where in the brain is Broca’s area?
Frontal lobe
If someone is unable to form language properly, what part of the brain is affected?
Broca’s Area, frontal lobe
Herman Von Helmholtz
Measured the speed of a nerve impulse
Who first measured the speed of a nerve impulse?
Herman Von Helmholtz
Sir Charles Sherrington
Discovered the existence of synapses
Who discovered the existence of synapses?
Sir Charles Sherrington
What was wrong with Sir Charles Sharrington’s understanding of synapses?
Thought transmission was electrical, now we know it is primarily chemical
Are sensory neurons afferent or efferent?
Afferent
What neurons transmit from body to the brain?
Sensory, afferent
Are motor neurons afferent or efferent?
Efferent
What neurons transmit from brain to the body?
Motor, efferent
Sensory neuron function
Transmit sensory information from receptors in the body to the brain and spinal cord
Motor neuron function
Transmit motor information from the brain and spinal cord to muscles and glands
What are interneurons and where are they primarily found?
Linked to reflexive behavior and are found mostly in the brain and spinal cord
What makes up the central nervous system?
Brain and spinal cord
What makes up the peripheral nervous system?
Nerve tissues and fibers outside the brain and spinal cord
What is the PNS broken into?
Somatic and Autonomic Systems
What is the autonomic system broken into?
Sympathetic and Parasympathetic systems
What part of the nervous system is the somatic system part of?
Peripheral
What part of the nervous system is the autonomic system part of?
Peripheral
What part of the nervous system is the sympathetic system part of?
Autonomic, Peripheral
What part of the nervous system is the parasympathetic system part of?
Autonomic, Peripheral
What is the function of the somatic system?
Sensory and motor information
What is the function of the autonomic system?
Involuntary and internal organ function
Which system is the fight or flight response?
Sympathetic system
Which system is the rest and digest response?
Parasympathetic
What activates the sympathetic system?
Stress
When one is stressed, what system is activated?
Sympathetic
What are meninges?
Thick sheath of connective tissue covering the brain
What tissue makes up the meninges?
Connective
What is the function of the meninges?
Protects the brain, anchors brain within the skull, reabsorbs CSF
What do the hindbrain and the Midbrain make up?
