According to Rilling (2014)‚ understanding the evolution of the unique characteristics of the human brain requires studying the brain of other living primate species. In other words‚ a specific evolutionary change in the human brain cannot be inferred to be unique to the human lineage unless other species sharing a last common ancestor don’t have it. That being said‚ Rilling emphasizes the role of comparative neuroimaging to investigate the similarities and differences between human and non-human

According to the National Institute of Neurology of Mexico‚ Officials say what could be the cause of these symptoms is‚ “[the] imbalance of right-left anterior cingulate cortex‚ which can lead to lack or excess of feelings of familiarity for a perception.” Which explains how a person with cotard delusion sees their own face and does not feel any familiarity or emotional attachment to their own self‚ and because

Mindful Meditation and the Brain Some view meditation as new age‚ hippie nonsense because it is not a social norm to sit in silence and dig beneath the surface of the mind. Others liken it to tuning an instrument before playing it. I subscribe to the latter; nonetheless‚ meditation is an ancient practice that can be traced back 2‚500 years. However‚ neuroscientists are just now beginning to measure the effects that it has on the brain. While there are many types of meditation‚ they all have the

flow produced by exercise also affects the anterior cingulate (relative to emotional tasks and linked to superior cognition in later life) which indicates a higher neuronal activity and metabolic rate. These factors contribute to quicker firing neurons as well as a greater capacity for memory retention. Studies have even proven that the parts of the brain responsible for critical thinking and memory‚ the prefrontal cortex and the medial temporal cortex‚ are shown to be enlarged in those with active

pathophysiology of ADHD is unclear and there are a number of competing theories.[87] Research on children with ADHD has shown a general reduction of brain volume‚ but with a proportionally greater reduction in the volume of the left-sided prefrontal cortex. These findings suggest that the core ADHD features of inattention‚ hyperactivity‚ and impulsivity may reflect frontal lobe dysfunction‚ but other brain regions particularly the cerebellum have also been implicated.[88] Neuroimaging studies in ADHD
