Exam 2 Flashcards
Four Lobes and functions?
Frontal - planning, evaluation
Pariental - touch, sensory, perception
Temporal - hearing, understanding language
Occipital - visual cortex, seeing
Three big brain principles?
Connectivity - Every part of your brain is connected (highways of brain)
Plasticity - Your brain can adapt and mold based on experiences (brain is malleable)
Specialization - different areas in the brain are specialized for different functions
Hippocampus function?
Learning and Memory.
Responsible for encoding and retrieving declarative memories (explicit)
Declarative memories (Explicit)
Memories of events/experiences. Stuff you will be encoding into LTM.
Non-declarative memories (Implicit)
Memories of everyday activities such as what you had for dinner. Enter STM but isn’t encoded into LTM.
Caudate Nucleus
Non-declarative memories encoded and retrieved. Also controls bodily functions.
Top-down processing?
Brain perceives info first then relays to body.
Bottom-up processing?
Body perceives info first then relays to brain
Prosopagnosia
face blindness - ppl can’t perceive faces as a whole. Retina sees it for these ppl so they can see different features but can’t put together. (Bottom-up works. Top-down doesn’t)
Fusiform Gyrus
Processes faces and useful for anything visually meaningful. Turned out was not just a place for processing faces but also anything you have expertise with.
capgras syndrome
When you see a familiar face, recognize it, but think they are an imposter, problem with connection from right fusiform gyrus to amygdala.
Amygdala
Processing fearful and threatening stimuli. Is in the subcortex (below the cerebral cortex). Subcortex is older.
Right ventral Cortex
Evaluation - Why can’t I recognize this face, conclusion: they must be an imposter.
Reductionism
Believe there is no such thing as a mind, they only believe in biology/brain.
Emergentism
Mind comes from context and social cues, but also biology
Broca’s Area
Area of brain for Speech production
Wernicke’s Area
Area of brain that understands language
Chunking
When you memorize things through grouping/breaking down into smaller bits because short term memory can only remember 7 +-2 things at a time.
Schema
Organized knowledge structure or a mental model we have stored in memory.
Maintenance Rehearsal
Straight repeating of information in order to memorize it. Encodes into LTM.
Elaborative Rehearsal
Elaborative rehearsal involves both linking the information to knowledge already stored and repeating the information.
Elaborative rehearsal is a way to more effectively memorize information and maintain it in your long-term memory.
Proactive Interference
When your prior knowledge interferes with new knowledge.
Retroactive Interference
When your new knowledge interferes with your prior knowledge.
What do Neurons do?
Talk to each other at the synapse. (Neuron 1 communicates info to neuron 2)
Action potential
electrical signals that travel within a neuron.
Axon
Tunnel within a neuron. Information travels through here to get to the other neuron.
Synapse
Structure that allows a neuron to pass a signal to another neuron.
Neurotransmitters
Neurotransmitters are chemical messengers in the body. Their job is to transmit signals from nerve cells to target cells.
Dendrite
Where a neuron receives input from other cells. (tree branch)
Pain and bottom-up and top-down processing
Painful stimuli is bottom-up. The way you interpret that stimuli in the brain is top-down.
Agonist
helps feel less pain. Closes the gate.
Antagonist
Makes you feel more pain. Opens the gate.
