The endocannabinoid (eCB) system has emerged as a central integrator linking the
perception of external and internal stimuli to distinct neurophysiological and
behavioural outcomes (such as fear reaction, anxiety and stress-coping), thus
allowing an organism to adapt to its changing environment. eCB signalling seems
to determine the value of fear-evoking stimuli and to tune appropriate
behavioural responses, which are essential for the organism’s long-term
viability, homeostasis and stress resilience; and dysregulation of eCB signalling
can lead to psychiatric disorders. An understanding of the underlying neural cell
populations and cellular processes enables the development of therapeutic
strategies to mitigate behavioural maladaptation.
