Neural Correlates of Fear in the Periaqueductal Gray
The dorsal and ventral periaqueductal gray (dPAG and vPAG, respectively) are embedded in distinct survival networks that coordinate, respectively, innate and conditioned fear-evoked freezing. However, the information encoded by the PAG during these survival behaviors is poorly understood. Recordings in the dPAG and vPAG in rats revealed differences in neuronal activity associated with the two b...
متن کاملAnatomical connections of the periaqueductal gray: specific neural substrates for different kinds of fear.
The periaqueductal gray (PAG) has been traditionally considered to be an exit relay for defensive responses. Functional mapping of its subdivisions has advanced our knowledge of this structure, but synthesis remains difficult mainly because results from lesion and stimulation studies have not correlated perfectly. After using a strategy that combined both techniques and a reevaluation of the av...
متن کاملPERIAQUEDUCTAL GRAY 1 Running head: PERIAQUEDUCTAL GRAY Common representation of pain and negative emotion in the midbrain periaqueductal gray
Human neuroimaging offers a powerful way to connect animal and human research on emotion, with profound implications for psychological science. However, the gulf between animal and human studies remains a formidable obstacle: Human studies typically focus on the cortex and a few subcortical regions such as the amygdala, whereas deeper structures such as the brainstem periaqueductal gray (PAG) p...
متن کاملThe Periaqueductal Gray (PAG)
This issue covers a broad territory of PAG function: neu-ropharmacology, functional organization, and PAG plasticity in adaptive behavior, emotion, anxiety, and the less-studied plasticity of the PAG function in females. Interest in the involvement of PAG in defensive behavior has a long history. Thinking about this area was radically changed by the seminal contributions of Bandler and DePaulis...
متن کاملRole of amygdala in conditioned and unconditioned fear generated in the periaqueductal gray.
The amygdala and ventral portion of the periaqueductal gray (vPAG) are crucial for the expression of the contextual freezing behavior. However, it is still unclear whether the amygdala also plays a role in defensive behaviors induced by electrical stimulation of the dorsal periaqueductal gray (dPAG). In the present study, rats were implanted with electrodes into dPAG for determination of the th...
