Ap Psych Flashcards
how we interpret those sensations is influenced by our available knowledge, our experiences, and our thoughts. An example of this is if you see the chair you have stubbed your toe on before and you avoid it to make sure it does not happen again.
top-down processing
when sensory receptors pick up signals for the brain to integrate and process. An example of this is stubbing your toe on a chair, the pain receptors detect pain and send this information to the brain where it is processed
Bottom up processing
layer of fat that encases many axons in the nervous system, increasing the speed at which messages are sent
Myelin Sheath
the spreading or transmission of information, behaviors, emotions, or psychological traits from one individual to another or within a group or society
Propagation
imaging procedures that use special x-ray equipment to create detailed pictures, or scans, of areas inside the body.
A CT (CAT) scan
Radioactive glucose tracked down to show metabolism by the brain
Pet scan
Electrodes placed on head and graphical image is produced
EEG
responsible for receiving sensory input from the external world, processing and transmitting this information throughout the body
neuron
Basic unit of the nervous system
Neurons
Responsible for maintaining balance and coordination
Cerebellum
branch-like structures that receive messages from other neurons and transmit them towards the cell body
Dentrites
neuroimaging technique that uses magnetic fields and radio waves to create detailed images of the brain’s structure and function.
MRI
Measures change in blood flow and creates 3D image
fMRI
The ability of neural networks in the brain to change through growth and reorganization.
Neuroplasticity
in-depth study of an individual or a small group
Case study
