Flashcards in Psychology: Biological Basis Deck (71):
A rod went through his head. The injury didn't kill him, caused major personality changes. This renewed the desire to study the brain.
Records brain wave activity
Computerized Tomography (CT)
Takes X-ray images of the brain
Position Emission Tomography (PET)
Shows the brain's activity by tracking radioactive glucose
Magnetic Resonance Imaging (MRI)
Takes a detailed images of the brains soft tissue by aligning spinning atoms in a magnetic field
Located where spinal chord goes into cranium.
Swelling at tip of the spinal chord. Controls involuntary action
Controls fine coordinated motor activity
Bridge from brain stem to cortex. Carries sensory information to cortex.
Takes incoming neuro information and channels it to cortex. Also involved in muscle tone and helps in sleep, wakefulness, and attention.
Most complex part of brain. Separates humans from animals
Folds in the brain. Memories stored within
Processes visual information
Processes information of pain, touch, and pressure
Largest part of the cortex. Involved in speech, future thought, and planning
Regulates sleep and wakefulness
Relay station for visual, auditory, and somatosensory information
Controls drives such as hunger, thirst, etc.
Emotions and emotion laden memories. Adds emotion to memory
Stores short term memories and takes them to long term
Connects the hemispheres of the brain
Surface layer of the brain. Separates humans from animals
Controls voluntary movements.
Processes body sensations
Interprets auditory information
Controls ability to speak
Spatial-visual tasks, facial recognition and creativity.
Language, logic, and sequential tasks
Largest part of the brain. Divided into two hemispheres
Primitive part of the brain.
Consists of brain and spinal chord
Divided into Somatic & Automatic
Glands and internal organs.
Gets the body ready for action
Brings the body back to homeostasis or normal
Basic unit of the nervous system.
Opening in the eye, adjusts to amount of light.
Point of clearest vision in the eye
Point of the eye with no rods and cones
Point of transduction in the eye
Takes information to the brain to be interpreted.
Receptors for black & white vision
Receptors that perceive color.
Colored part of the eye that controls the size of the pupil.
Transparent protective covering over the eye
Sends image to the retina.
Caused by vibrating objects that produce sound waves.
External part of the ear, helps catch sound waves.
Takes sound from pinna to ear drum.
Also called eardrum, vibrates when sound hits it.
Three bones in inner ear that transmit sound to the cochlea.
Area of transduction in ear.
By fluid movement trigger neural impulses
Takes information to the temporal lobe for interpretation.
Differences in pitch result from stimulation of different areas of the cochlea.
Differences in pitch are due to rate of impulses traveling up the auditory nerve.
There are three types of cones: red, blue, & green. All colors are a combination of the three.
Colors are analyzed in opponent colors. The thalamus turns the colors in and off.
Only sense that doesn't undergo transduction
What we come to expect from a stimulus
We fill in gaps in perception
Conscious focusing on a particular stimulus
We always see the strongest stimulus first
Looks for patterns in perception
Objects appear fuzzy in the distance
Both eyes see slightly different stimuli
Awareness of three dimensions
Tendency to group things on the basis of how close they are to each other
