Neuro Lab 1

Consists of higher-order heteromodal association cortex (Mostly prefrontal cortex). The frontal lobe is important in restraining behaviors, initiative, order & sequence.

Region of speech production in dominant hemisphere (95% right-handers and 70% left-handers).

Superior and Inferior; divide the 3 frontal gyri.

Located in the Precentral Gyrus; it represents body regions in the Primary Motor cortex; point of origin of the corticospinal tract

Separates pre- from post-central gyrus.

Auditory perception, language perception; plays a key role in the formation of long-term memories (via the hippocampus).

It separates the frontal and parietal lobes from the temporal lobe.

Comprehension of language in the dominant hemisphere; it encircles the primary auditory cortex.

Process auditory input, including volume and pitch.

It is the interoceptive center; regulation of emotions, autonomic, motor and sensory processing.

It integrates sensory information, including modalities that determine spatial relationships.

The sensory homunculus is present in the postcentral gyrus (Brodmann areas 3, 1 and 2).

Posterior to the Post-central gyrus.

Horizontal and Oblique portions; cortical areas surrounding it are involved in numerical, spatial and symbols perception.

Processing of visual input, including color, frequency of electromagnetic waves, and spatial relationships.

Largest cerebral commissural fiber bundle; interconnects the cerebral hemispheres.

Involved in Limbic circuitries (including Papez).

Supplementary motor area (involve in motor planning).

Separates the paracentral gyri from the Precuneus.

Regulates visuospatial imagery; episodic memory; visual imagery of self.

Separates the Parietal and Occipital Lobes.

Provides with basic visual processing.

Primary visual cortex location.

Part of the frontal lobe; function is unclear.

Groove occupied by Olfactory Nerve.

C.N. I. Provides olfaction; purely sensory.

C.N. II. Conveys visual input; purely sensory. Nasal fibers of C.N.II decussate at the chiasm, and becomes the optic tract.

• Associated with vagal processing.
• Inferior Temporal Gyrus: Involved in complex visual processing.

Involved in visual processing; recognition of face and body.

Processing of visual background and scenery.

Anterior flexure of the Parahippocampal gyrus. Point of origin of seizures with olfactory hallucinations.

Gray matter with multiple openings for arteries supplying internal capsule and other structures.
