‘Math neurons’ identified in the brain

The brain has neurons that fire specifically during certain mathematical operations. The findings indicate that some of the neurons detected are active exclusively during additions, while others are active during subtractions. They respond in the same …

Transient BP spikes coupled to learning in brain

Minor everyday rises in blood pressure due to short-term stressors can be linked to a brain area that controls conscious and learned motor skills. This discovery paves the way for a chance to influence the rises in blood pressure and, in the long run, …
