text: 'Orientation in space is represented in specialized brain circuits. Persistent
head direction signals are transmitted from anterior thalamus to the presubiculum,
but the identity of the presubicular target neurons, their connectivity and function
in local microcircuits are unknown. Here, we examine how thalamic afferents recruit
presubicular principal neurons and Martinotti interneurons, and the ensuing synaptic
interactions between these cells. Pyramidal neuron activation of Martinotti cells
in superficial layers is strongly facilitating such that high-frequency head directional
stimulation efficiently unmutes synaptic excitation. Martinotti-cell feedback
plays a dual role: precisely timed spikes may not inhibit the firing of in-tune
head direction cells, while exerting lateral inhibition. Autonomous attractor
dynamics emerge from a modelled network implementing wiring motifs and timing
sensitive synaptic interactions in the pyramidal - Martinotti-cell feedback loop.
This inhibitory microcircuit is therefore tuned to refine and maintain head direction
information in the presubiculum.'
