The emergence of subjective feelings during foraging under predation threat
Non-human approach-avoidance conflict tests are classic paradigms to elicit anxiety-like behaviours, and mimick aspects of foraging for food while under threat of predation. We have recently translated this class of paradigms to humans (e. g. Bach et al. 2014, Current Biology; Korn et al. 2017, Biological Psychiatry). However, it is unclear how behaviour in this paradigm relates to subjective feeling.
Single-unit activity of human amygdala neurons during fear conditioning
Fear conditioning is a form of aversive associative learning that relies on synaptic plasticity in the amygdala. Non-human electrophysiological studies have revealed a role of theta and gamma oscillations in this process (Seidenbecher et al. 2003, Science, Stujenske et al. 2014, Neuron) but recent human MEG research from our own lab indicates species differences. We have now gathered LFP and single-unit data from human intracranial recordings on pre-surgical epileptic patients.
