The amygdalae are a pair of small brain structures, each of which is composed of three main
subregions and whose function is implicated in neuropsychiatric conditions. Functional …

Mapping the structural and functional connectivity of the central nervous system has become
a key area within neuroimaging research. While detailed network structures across the …

Over the past decades, studies of fear learning and extinction have advanced our
understanding of the neurobiology of threat and safety learning. Animal studies can provide …

Three subregions of the amygdala receive monosynaptic projections from the olfactory bulb,
making them part of primary olfactory cortex. These primary olfactory areas are located at the …

Prediction error (PE) is the mismatch between a prior expectation and reality, and it lies at
the core of associative learning about aversive and appetitive stimuli. Human studies on fear …

Reading danger signals may save an animal's life, and learning about threats from others
