Here we study the mechanism of this unconsciously mediated emotional learning. We measured neural activity in volunteer subjects who were presented with two angry faces, one of which, through previous classical conditioning, was associated with a burst of white noise. In half of the trials, the ...
Conscious and unconscious emotional learning in the human amygdala.Presents research which studied the mechanism of unconsciously mediated emotional learning. Subjects' response to an angry face; Measurements of neural activity; The human amygdala discriminating between stimuli; Lateralized response in the ...
Fear conditioning is a valuable behavioral paradigm for studying the neural basis of emotional learning and memory. The lateral nucleus of the amygdala (LA) is a crucial site of neural changes that occur during fear conditioning. Pharmacological manipulations of the LA, strategically timed with respec...
The amygdala's response to fear faces irrespective of awareness and attentional focus has led some to propose that the amygdala is detecting threat stimuli via a subcortical pathway that bypasses visual cortex (see the section on “Implicit Emotional Learning and Memory” for a description). In ...
Introduction: Many evidences have suggested that the Basolateral Amygdala (BLA) are probably involved in emotional learning and modulation of spatial memory processes. The aim of this present study was assessment of the effect of reversible abolition of BLA on spatial memory processes in a place ...
A limbic brain area, the amygdala plays a key role in emotional responses and affective states and disorders such as learned fear, anxiety, and depression. The amygdala has also emerged as an important brain center for the emotional–affective dimension of pain and for pain modulation. Hyperactivi...
They are implicated in reward evaluation of stimuli and emotional learning (Burdach 1819–1822; Johnston 1923; Loo 1930; Weiskrantz 1956; Price et al. 1987; De Olmos et al. 1985, 2004; Alheid et al. 1995; Gloor 1997; Swanson and Petrovich 1998; Amaral et al. 2003; Sah et al. ...

A subcortical pathway is assumed to mediate non-conscious visual processing of emotional stimuli. In this provocative Perspective, Pessoa and Adolphs argue that this pathway does not exist in primates and propose novel roles for the amygdala and the cort
