QUESTIONS AND ANSWERS
2026 - 2027
What are the 3 levels at which any machine carrying out an information-
processing task must undergo - ANSWERS-computational theory (goal
is to determine the shape of objects in the world), representation and
algorithm, hardware implementation (neurons)
What is the LGN? What are the 3 types of cells it contains? -
ANSWERS-It is the lateral geneculent nucleus. The three kinds of cells
are P-type ganglion (parvocellular), M-type ganglion (Maynocellular),
and nonM-nonP ganglion cells (koniocellular)
P-type cells - ANSWERS-deal with shape, located in layers 4, 5, and 6
M-type cells - ANSWERS-deal with motion, located in layers 1 and 2
nonM-nonP cells - ANSWERS-deal with color, found in between each
of these 3 layers
What did Hubel and Wiesel discover? - ANSWERS-simple and complex
cells in the visual cortex

QUESTIONS AND ANSWERS
2026 - 2027
simple cells - ANSWERS-used to detect orientation
complex cells - ANSWERS-deal with directional sensitivity
What are the different visual pathways? - ANSWERS-dorsal pathways
("where" information) and the ventral pathway ('What" information)
brain-machine interface - ANSWERS-a system that detects, generates,
and/or modifies ongoing neural activity in the brain to accomplish some
task
brain machine interfaces can use ______ to control artificial eflectors -
ANSWERS-neural signals
What is cognitive psychology? - ANSWERS-memory systems, case
studies, and its theoretical applications

QUESTIONS AND ANSWERS
2026 - 2027
what is memory? - ANSWERS-it is a bedrock, the foundation upon
which we think about the world, experiences are rooted in memory and
we are collectors of experiences , it becomes more salient when it is tied
to emotion, it links us to the past and the future
where is memory located? - ANSWERS-short term memory is located in
the cerebral cortex, long term memory is scattered throughout the brain
Karl Lashley - ANSWERS-He was an American psychologist and
behaviorist well-remembered for his influential contributions to the
study of learning and memory. His failure to find a single biological
locus of memory in the rat's brain (or "engram", as he called it)
suggested to him that memories were not localized to one part of the
brain, but were widely distributed throughout the cerebral cortex.
synaptic plasticity - ANSWERS-learning in a nervous system requires a
change in the structure or biochemistry of a synapse
