The amygdala is one of the best-understood brain regions with regard to differences between the sexes. The amygdala is larger in males than females, in children aged 7 to 11, [19] adult humans, [20] and adult rats. [21] There is considerable growth within the first few years of structural development in both male and female amygdalae. [22]
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 ...
Parental brain. Parental experience, as well as changing hormone levels during pregnancy and postpartum, cause changes in the parental brain. [1] Displaying maternal sensitivity towards infant cues, processing those cues and being motivated to engage socially with her infant and attend to the infant's needs in any context could be described as ...
Fear can be evoked by two systems in the brain, both involving the thalamus and the amygdala: one old, short and fast, the other more recently evolved, more circuitous and slower. In the older system, sensory information travels directly and quickly from the thalamus to the amygdala where it elicits the autonomic and motor responses we call fear.
Paternal brain. Changing hormone levels during pregnancy and postpartum as well as parental experience cause changes in the parental brain. Both the father and mother undergo distinct biological changes as they transition to parents, but the changes that occur in the paternal brain are not as well studied. Similar to the changes that occur in ...
Bruce & Young Model of Face Recognition, 1986. One of the most widely accepted theories of face perception argues that understanding faces involves several stages: [7] from basic perceptual manipulations on the sensory information to derive details about the person (such as age, gender or attractiveness), to being able to recall meaningful details such as their name and any relevant past ...
Healthy development early in life is critical. Early life is characterized by rapid development and increased susceptibility to modifications. Childhood trauma can severely affect the development of the brain, resulting in the alteration of neural circuits which are involved in emotional regulation and threat detection.
Childhood amnesia. Childhood amnesia, also called infantile amnesia, is the inability of adults to retrieve episodic memories (memories of situations or events) before the age of three to four years. It may also refer to the scarcity or fragmentation of memories recollected from early childhood, particularly occurring between the ages of 3 and 6.
