Whitening a data matrix follows the same transformation as for random variables. An empirical whitening transform is obtained by estimating the covariance (e.g. by maximum likelihood) and subsequently constructing a corresponding estimated whitening matrix (e.g. by Cholesky decomposition).
Although the brain becomes aware of the stimulation in a few seconds, it is unknown how the gut determines the caloric sugar to influence choice. A new cell was identified - a neuropod, an intestinal transducer. [7] This cell synapses with the vagus to instantly alert the brain to the presence of glucose in the gut. [8]
Grains of white sugar White sugar is often sold and used as cubes A bowl of white sugar. White sugar, also called table sugar, granulated sugar, or regular sugar, is a commonly used type of sugar, made either of beet sugar or cane sugar, which has undergone a refining process. It is nearly pure sucrose.
Relatively speaking, the brain consumes an immense amount of energy in comparison to the rest of the body. The mechanisms involved in the transfer of energy from foods to neurons are likely to be fundamental to the control of brain function. [1] Human bodily processes, including the brain, all require both macronutrients, as well as ...
Poor diet in early childhood affects the number of neurons in parts of the brain. [1]Nutritional neuroscience is the scientific discipline that studies the effects various components of the diet such as minerals, vitamins, protein, carbohydrates, fats, dietary supplements, synthetic hormones, and food additives have on neurochemistry, neurobiology, behavior, and cognition.
A diet high in sugary foods can affect brain development in children. carlosgaw/iStock via Getty Images PlusParents often stress about their kids’ sugar intake, but it can be hard to know how ...
Functional integration is the study of how brain regions work together to process information and effect responses. Though functional integration frequently relies on anatomic knowledge of the connections between brain areas, the emphasis is on how large clusters of neurons – numbering in the thousands or millions – fire together under various stimuli.
In cognitive psychology, information processing is an approach to the goal of understanding human thinking that treats cognition as essentially computational in nature, with the mind being the software and the brain being the hardware. [1] It arose in the 1940s and 1950s, after World War II. [2]
