Pascale Michelon What is cog­ni­tion? Cog­ni­tion has to do with how a per­son under­stands the world and acts in it. It is the set of men­tal abil­i­ties or process­es that are part of near­ly every human action while we are awake. Cog­ni­tive abil­i­ties are brain-based skills we need to car­ry out any task from the sim­plest to the most com­plex. Cog­ni­tive abil­i­ties or skills are sup­port­ed by spe­cif­ic neu­ronal net­works.

In the table below you can browse through the main brain func­tions involved in cog­ni­tion. With age, some cog­ni­tive abil­i­ties tend to decline, espe­cial­ly the so-called exec­u­tive func­tions, The different type of cognitive abilities.

In a study done at the University of British Columbia, researchers found that regular aerobic exercise, the kind that gets your heart and your sweat glands pumping, appears to boost the size of the hippocampus, the brain area involved in verbal memory and learning. Resistance training, balance and muscle toning exercises did not have the same results. The finding comes at a critical time. Active older adults less likely to become cognitively impaired, UF researchers find. An in-depth presentation on the impact of exercise on cognitive functioning by Dr Amy Jak. Hippocampal and Cerebral Blood Flow after Exercise Cessation in Master Athletes.

Introduction Endurance exercise training (exercise) produces physiological adaptations that enhance aerobic fitness and cardiovascular health (Brooks et al., 1996).

Hippocampal and Cerebral Blood Flow after Exercise Cessation in Master Athletes

Consistent exercise effectively augments the maximal rate of oxygen consumption (O2max) centrally, by increasing cardiac output, and/or peripherally by widening the arterial-venous oxygen (A-O2) difference (Seals et al., 1981). O2max is the gold-standard index of cardiorespiratory fitness and is highly correlated with both morbidity and mortality (Hoekstra et al., 2008; Sawada et al., 2012), with greater fitness status associated with a reduced risk of chronic disease and a longer lifespan. In addition to enhancing the function of the cardiovascular system, exercise has been shown to increase bone density, improve muscle quality, and protect against metabolic dysfunction (Brooks et al., 1996). A growing body of empirical evidence supports the notion that exercise also robustly affects the human brain. Methods Participants. Inactivity can also cause a decrease in strength and stamina, making one more susceptible to chronic diseases.

By age 70, one in six people has mild cognitive impairment (which can progress to Alzheimer's disease). Up until about two decades ago, it was believed that your brain only produced new cells early in life. But research has shown that the brain has the ability to change throughout your entire life span, growing new cells, making new connections, and even increasing in size.

Eight Habits That Improve Cognitive Function

Science Isn’t Sure. " I believe the answer is no. Without a variety of other daily habits, these "brain-training" games cannot stave off mental decline or dramatically improve cognitive function. Most of these brain-training games will have some benefits, but it's impossible to optimize brain connectivity and maximize neurogenesis (growth of new neurons) sitting in a chair while playing a video game on a two-dimensional screen. In order to give your brain a full workout, you need to engage both hemispheres of the cerebrum, and of the cerebellum.
