Cortical white matter increases from childhood (~9 years) to adolescence (~14 years), most notably in the frontal and parietal cortices. [8] Cortical grey matter development peaks at ~12 years of age in the frontal and parietal cortices, and 14–16 years in the temporal lobes (with the superior temporal cortex being last to mature), peaking at ...
Trochlear nerve (cranial nerve 4) – eye rotation. Trigeminal nerve (cranial nerve 5) – sensation from the face and certain motor functions such as biting and chewing. Abducens nerve (cranial nerve 6) – certain eye rotation. Facial nerve (cranial nerve 7) – facial expression and taste sensations from the tongue.
Aging of the brain is a process of transformation of the brain in older age, including changes all individuals experience and those of illness (including unrecognised illness). Usually this refers to humans. Since life extension is only pertinent if accompanied by health span extension, and, more importantly, by preserving brain health and ...
Brain–body mass ratio, also known as the brain–body weight ratio, is the ratio of brain mass to body mass, which is hypothesized to be a rough estimate of the intelligence of an animal, although fairly inaccurate in many cases. A more complex measurement, encephalization quotient, takes into account allometric effects of widely divergent ...
Erik Erikson and Carl Jung proposed stage theories of human development that encompass the entire life span, and emphasized the potential for positive change very late in life. The concept of adulthood has legal and socio-cultural definitions. The legal definition of an adult is a person who is fully grown or developed.
Paul B. Baltes (18 June 1939 – 7 November 2006) was a German psychologist whose broad scientific agenda was devoted to establishing and promoting the life-span orientation of human development. He was also a theorist in the field of the psychology of aging. He has been described by American Psychologist as one of the most influential ...
Encephalization quotient. Encephalization quotient (EQ), encephalization level (EL), or just encephalization is a relative brain size measure that is defined as the ratio between observed and predicted brain mass for an animal of a given size, based on nonlinear regression on a range of reference species. [1][2] It has been used as a proxy for ...
Some more common traits include: Avoidance of eye contact – preference to avoid eye contact and feelings of fear or being overwhelmed when looking into someone's eyes. Developmental delay – slower acquisition of life skills. Emotional dysregulation – mood swings, including outbursts when overwhelmed. Executive dysfunction – difficulty ...
