Electrical stimulation of midbrain tectum structures, particularly the dorsal periaqueductal
gray (dPAG) and inferior colliculus (IC), produces defensive responses, such as freezing …

The present study investigated the involvement of H (1) histaminegic receptor on the
acquisition of inhibitory avoidance in Carassius auratus submitted to telencephalic ablation …

Gradual increases in the electrical stimulation of the inferior colliculus produces progressive
aversive responses from vigilance, through freezing, until escape. These responses are …

A expressão de respostas de medo condicionadas e incondicionadas geradas por
estímulos auditivos de natureza aversiva envolve a transmissão neural do colículo inferior …

Classic experiments suggested that the midbrain reticular formation plays an important role
in the induction and maintenance of high-frequency, low-amplitude activation of the …

Consistent evidence has shown that learning may be produced in paradigms using
electrical stimulation of the inferior colliculus as unconditioned stimulus (US). Much …

Consistent evidence has shown that dopamine release in the prefrontal cortex is increased
by electrical stimulation of the inferior colliculus (IC) as unconditioned stimulus. Recent …

Electrical stimulation of midbrain tectum structures, particularly the dorsal periaqueductal
gray (dPAG) and inferior colliculus (IC), produces defensive responses, such as freezing …

In recent years, clear links have been shown between high and low reactive infant
temperaments (defined by distinct behavioral responses to unfamiliar stimuli at four months) …

Background: The defence network is a network of brain structures that are activated when a
person experiences fear or anxiety. Structures in this network, such as the amygdala, locus …
