5 unusual facts about cerebral cortex


André Leroi-Gourhan

Crucial to Leroi-Gourhan's understanding of human evolution is the notion that the transition to bipedality freed the hands for grasping, and the face for gesturing and speaking, and thus that the development of the cortex, of technology, and of language all follow from the adoption of an upright stance.

Deepak Pandya

During his postdoctoral fellowship and subsequent period in Boston, Pandya focused his research investigations on cortico-cortical connections.

Louis Jacobsohn-Lask

In 1899 Jacobsohn and Edward Flatau wrote Handbuch der Anatomie und vergleichenden Anatomie des Centralnervensystems der Säugetiere, which included one of first attempts to classify sulci and gyri of human brain cortex.

Memory-prediction framework

It is proposed that the motor areas of the cortex consist of a behavioural hierarchy similar to the sensory hierarchy, with the lowest levels consisting of explicit motor commands to musculature and the highest levels corresponding to abstract prescriptions (e.g. 'resize the browser').

Semantic satiation

The explanation for the phenomenon was that verbal repetition repeatedly aroused a specific neural pattern in the cortex which corresponds to the meaning of the word.


Adrian Owen

His post-doctoral research on working memory with Michael Petrides, (PNAS, Cerebral Cortex, Journal of Cognitive Neuroscience, Brain and others) was instrumental in refuting the then prevailing view of lateral frontal-lobe organisation advanced by Patricia Goldman-Rakic and others, and is still widely cited in that context.

Electrical brain stimulation

The stimulation of the surface of the cerebral cortex by using brain stimulation was used to investigate the motor cortex in animals by researchers such as Eduard Hitzig (1838–1907), Gustav Fritsch (1838–1927), David Ferrier (1842–1928) and Friedrich Goltz (1834–1902).

Latexin family

Latexin, a protein possessing inhibitory activity against rat carboxypeptidase A1 (CPA1) and CPA2 (MEROPS peptidase family M14A), is expressed in a neuronal subset in the cerebral cortex and cells in other neural and non-neural tissues of rat.

Posterior limb of internal capsule

The anterior two-thirds of the occipital part of the internal capsule contains fibers of the corticospinal tract, which arise in the motor area of the cerebral cortex and, passing downward through the middle three-fifths of the base of the cerebral peduncle, are continued into the pyramids of the medulla oblongata.

Cerebral organoid

These specific regions can be even further specified by markers AUTS2, TSHZ2, and LMO4 with the first representing cerebral cortex and the two after representing the occipital lobe.

Pathoclisis

Cécile Vogt-Mugnier and her husband Oskar Vogt came up with the idea of pathoclisis through their research on insects and the human cerebral cortex.

Synaptosome

In a collaborative study with the electron microscopist George Gray from University College London, Victor P. Whittaker eventually showed that the acetylcholine-rich particles derived from guinea-pig cerebral cortex were synaptic vesicle-rich pinched-off nerve terminals.
