4. 3. The amygdala, experimental anxiety and alcohol consumption : an integrative study in the rat

   Författare :Christian Möller; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Amygdala; Anxiety; Alcoholism; Behaviour; Rat;

   Sammanfattning : The amygdala integrates emotionally relevant stimuli. Here, the aversive value of stimuli and memories is extracted and transduced into a behavioral response. This rapid processing leads to a coordinated activation of autonomic, endocrine, behavioral and emotional functions that together comprise the fear reaction. LÄS MER
