Sensory Pathways to the Cortex Bio 6

Flashcards covering key terms and definitions related to the sensory pathways to the cortex.

Lateral Geniculate Nucleus (LGN)

A structure in the thalamus that relays visual information to the primary visual cortex.

Calcarine Sulcus

A groove in the brain where the primary visual cortex is located.

Somatosensory Homunculus

A representation of the body in the brain that indicates the relative size of body parts based on their sensitivity.

Phantom Limb Syndrome

The perception of sensations in a missing limb following amputation due to brain's persistent cortical representations.

Centre-Surround Receptive Fields

Neuronal receptive fields that respond to contrast between stimuli in the center and surrounding area, aiding in edge detection.

Receptive Field

The specific area from which stimuli can influence the firing rate of a neuron.

Scotoma

An area of reduced vision or a 'blind spot' that corresponds to damage in the visual cortex.

Wilder Penfield

A Canadian neurosurgeon known for mapping the sensory and motor cortices using electrical stimulation.

Neuropsychology

The study of the relationship between brain function and behavior.

Neuroimaging Techniques

Methods like fMRI and PET that visualize brain activity and structure.
