Neuroscience milestone – Vernon Mountcastle’s discovery of columnar organization of the neurocortex.

Brain neuron organization has been investigated since a long time and it had been very confusing for scientists trying to determine the organization among a mass of neurons. Vernon Mountcastle’s discovery of a column of neuron paved the way for understanding of the brain. In 1957 he made the radical discovery that the columnar pattern is repeated all over the cortex and proposing that unit as a basic formation. He also hypothesized that this columnar structure may be repeated within itself too and he has been proven right even though there may be some changes in height due to interconnections between the neurons. Ray Kurzweil in “How to create the mind” proposed that this basic column may be a pattern recognizer that is responsible for memory and advanced thought and metaphors.

Watch the video of Vernon Mountcastle’s interview below. It was taken in 1997 and is about 55 minutes long.

    Schizophrenia is mental disorder characterized by problems in thinking, perception, emotions and behavior. It requires long term medication to manage symptoms. There are many drugs in the market to treat schizophrenia: Antipsychotics: These block the dopamine D2 receptor, though with side effects such as tremors and tardive dyskinesia. The Atypical antipsychotics affect both the dopamine…

    A synthetic biology company called Huue is going forward to create dye’s from bacteria. The cool part is that they are taking machinery that is in plants and introducing them into bacteria.An advantage is that you could manipulate and then come up with new dyes. The dye Huue has started with is called Indigo and…

    Alzhiemer’s psychosis

    Alzheimer’s psychosis is distinct from the slow progression of Alzheimer’s and indicates a more severe phenotype in which cognitive decline starts even before psychosis onset. It is thought to originate/localized in neocortex rather than medial temporal lobe. There is currently only one drug that targets Alzheimer’s psychosis. It is called Rexulti (Brexipipazole). It is specifically…
