UPDATE!!
What is cortical blindness? - (ANSWER)Partial damage to the primary visual cortex causing loss of some
visual field due to retinotopy.
What are photopigments? - (ANSWER)Substances present in photoreceptors (cones) that are
responsible for color sensitivity.
What are the three classes of cones and their peak sensitivities? - (ANSWER)Short (S) - 420nm (blue),
Medium (M) - 530nm (green), Long (L) - 560nm (yellow).
Where are the genes for M and L photopigments located? - (ANSWER)On the X chromosome.
What is the function of spectrally opponent ganglion cells? - (ANSWER)They receive inputs from
different types of cones (M or L) and record the difference.
What is the ventral path in visual processing? - (ANSWER)The pathway from V2 to V4 to the inferior
temporal lobe (IT) responsible for object and face recognition.
What is the role of the fusiform face area (FFA)? - (ANSWER)It is important for recognizing faces and
emotions on faces.
What is visual agnosia? - (ANSWER)A defect in object recognition for visual stimuli.
What is prosopagnosia? - (ANSWER)The inability to recognize faces.
What is the function of the dorsal path? - (ANSWER)To detect where objects are and how they move,
involving areas like MT/V5 and MST.
What is optic ataxia? - (ANSWER)Difficulty using vision to reach for an object due to damage in the
posterior parietal cortex.

UPDATE!!
What is overt attention? - (ANSWER)Directing our senses and attention toward the same target.
What is covert attention? - (ANSWER)Shifting focus of visual attention without moving the eyes.
What is bottom-up processing? - (ANSWER)Attention driven by external stimuli (sensations).
What is inattentional blindness? - (ANSWER)Failing to perceive non-attending stimuli, even if they are
very obvious.
What is declarative memory? - (ANSWER)Memory that deals with 'what'; facts and information acquired
through learning.
What are the two types of declarative memory? - (ANSWER)Episodic memory (personal facts) and
semantic memory (general knowledge).
What is nondeclarative memory? - (ANSWER)Memory that deals with 'how'; shown by performance
rather than conscious recollection.
What is the role of the medial temporal lobe in memory? - (ANSWER)It is crucial for the formation of
declarative memories.
What is the function of long-term potentiation (LTP)? - (ANSWER)It is a stable and enduring increase in
the effectiveness of synapses.
What are the pathological features of Alzheimer's disease? - (ANSWER)Senile plaques with extracellular
Amyloid beta (Aβ) and intracellular neurofibrillary tangles (NFTs) with hyperphosphorylated Tau (P-Tau).
What is the mesolimbic pathway? - (ANSWER)Dopaminergic neurons from the VTA target the nucleus
accumbens (NAc) and prefrontal cortex (PFC), involved in reward processing.
