Significantly, these regions namely the ventral striatum, dorsal anterior cingulate and amygdale
, were regions that are also particularly activated in drug addicts when shown drug stimuli.
Regional cerebral blood flow in amygdale
and medial prefrontal cortex during traumatic imagery in male and female Vietnam veterans with PTSD.
It found out that there was a weak connection between the amygdale
and the orbitofrontal cortex.
He keeps his amygdale
in check and doesn't let fear rule his decisions.
Recent studies implicate the prelimbic cortex in fear expression as well, by way of its connection to the basal and then to central nucleus of amygdale
Eugene, Joormann, Cooney, Atlas, and Gotlib (2010) highlight the importance of assessing activation in the rostral anterior cingulated cortex, whereas Johnstone, van Reekum, Urry, Kalin, and Davidson (2007) found that depressed individuals were characterized by increased dorsolateral prefrontal cortex activation (cognition and negative symptoms) and decreased amygdale
activation that appeared to be mediated by the ventromedial prefrontal cortex (affect and negative symptoms).
The hydrothermal pathways may have been substantially different, even for quite closely spaced cavities It is probable that a variation in the nature of the exchangeable cations in zeolites occurred within a single amygdale
or vein Fluid composition may be important in defining the type of zeolite that occurs in a particular amygdale
or vein, whereas temperature variations may influence chemical variation within such individual cavities.
22) Oxytocin receptor-expressing neural circuits in the central amygdale
connect to the medial prefrontal cortex to suppress neurons that produce the freezing reaction to fear while promoting risk assessment and exploratory response to frightening stimulus.
The right amygdale
in men was activated significantly more than in women, whereas women activated fewer structures in the left amygdale
There is accumulated evidence that the amygdaloid complex of nuclei such as amygdale
, representing the central emotional management within the human brain, gives emotional (affective) tone to the input sensory information even before its conscious processing (Simic and Goran 2009).
Prefrontal cortex, basal ganglia, limbic system and amygdale
are words commonly found on WebMD.
In the case of chronic stress there is progressive damage to some structures of the nervous system and in particular there is an atrophy of the apical dendrite of the neurons of the hippocampus, of the amygdale
and damages to the dendrite of the neurons of the prefrontal cortex.
