The chair-holder will be expected to create links with industrial partners to accelerate translation of research results into improved health outcomes, while ensuring equitable access to the knowledge produced and to the social and health benefits that will flow from that knowledge. This program will study the critical role of the brain in the development of obesity and diabetes and address the important roles of disordered metabolism in the development and progression of neurodegenerative diseases. The goal of this CERC is to establish a cutting-edge research program at this interface. The CERC chair-holder will be mandated to build a multidisciplinary research team encompassing a diversity of lived experiences, identifies and career stages in the Faculty of Medicine and Health Sciences with expertise at the intersection of metabolic disorders and neuroscience. CERC awards are amongst the most prestigious and generous available globally. The CERC Program supports Canadian universities in their efforts to build upon Canada’s reputation as a global leader in research and innovation through recruitment of world-leading researchers to Canada. (Provided by: Webvision: The Organization of the Retina and Visual System.The Faculty of Medicine and Health Sciences at McGill University is seeking to recruit an internationally recognised scientist with a strong track record in innovation and research leadership to direct a new program in “Metabolism and the Brain” that is supported by a prestigious CERC award. A simple neuron from a light microscope capture. Fluorescently Tagged Primary Visual Cortex Neuron. Neurons within a minicolumn (microcolumn) encode similar features, whereas a hypercolumn “denotes a unit containing a full set of values for any given set of receptive field parameters.” Fig.9.10.1. Color-selective neurons live in blobs (regions of cortex that stain dark when you stain for cytochrome oxidase, because they’re metabolically rich) there’s a blob for each pinwheel.Ī cortical column is a group of neurons in the cortex of the brain that can be successively penetrated by a probe inserted perpendicularly to the cortical surface, and which have nearly identical receptive fields. Some V1 neurons are color-blind some are color-selective. A cluster of orientation columns is called a pinwheel-there’s an orientation pinwheel for each eye. This segregation is strongest in the input layer (4), so when we look for ODCs, we look in the middle of the cortex. Left and right eye inputs are segregated into ocular dominance columns. For V1, this means that as you move across the cortex, you find neurons with different orientation preferences. If you sample neural responses as you move across the surface, they change.This means that as you move down through cortex, you find neurons with the same orientation preferences. If you sample neural responses as you move through the depth, they stay approximately the same.The gray matter has 2 important directions: across the surface and through the depth. No modifications.)Ĭolumnar organization is an important property of primary sensory and motor cortices. (Credit: McGill: The Brain from Top to Bottom, Figure of hypercolumns, Copyleft. Blobs are color selective and for every pinwheel there is a blob. Orientation columns are neurons that get excited at different orientations and a cluster of these is called a pinwheel. Ocular dominance columns are segregated into left and right eye inputs. Know how the V1 neurons are organized according to their orientation preferences (depth vs surface).įigure 9.2. Know how the V1 neurons are organized according to eye of origin.
