Letter to NeuroscienceIncreased social fear and decreased fear of objects in monkeys with neonatal amygdala lesions
Section snippets
Subjects and living conditions
Six infant rhesus monkeys (Macaca mulatta) were used in this study. Three infants (two males, one female) received bilateral amygdala lesions at 14 days (±2 days) after birth, while the other three infants (two males, one female) served as controls. Infants were housed with their mothers in standard home cages (61 cm W×66 cm D×81 cm H) until they were on average 5.5 months old, when the mothers were removed. Following weaning, the infants remained in their home cage and were allowed access to

Amygdala connectivity and implications for social cognition and disorders
2022, Handbook of Clinical NeurologyCitation Excerpt :As stated above, the amygdala is ideally suited to play a role in a wide variety of social processes, given its extensive and reciprocal connections across the brain (Amaral and Price, 1984; Mcdonald, 1998; Sah et al., 2003). Furthermore, it has been implicated in a wide variety of behavioral processes, including fear-related processes (Cassell et al., 1986; Rizvi et al., 1991) and social cognition (Adolphs et al., 1994; Prather et al., 2001; Diergaarde et al., 2004; Machado and Bachevalier, 2006). It is therefore unsurprising that disruption of the amygdala or the amygdala circuitry results in a variety of neuropsychiatric disorders.
