Recent research suggests that Martinotti cells are associated with a cortical dampening mechanism. When the pyramidal neuron, which is the most common type of neuron in the brain, starts getting overexcited, Martinotti cells start sending inhibitory signals to the surrounding neurons.

They regulate pyramidal cell activity via a significant axonal arbor in layer 1 that forms synapses onto apical dendrites of pyramidal cells, modulating dendritic spike generation and synaptic integration, as well as FDDI between pyramidal cells (Murayama et al., 2009). | They regulate pyramidal cell activity via a significant axonal arbor in layer 1 that forms synapses onto apical dendrites of pyramidal cells, modulating dendritic spike generation and synaptic integration, as well as FDDI between pyramidal cells (Murayama et al., 2009).The probability of this disynaptic inhibition, around 20% in layer 5 frontal cortex of juvenile rats (Berger et al., 2009), suggests an underlying high degree of connectivity between Martinotti cells and pyramidal cells that is in line with the results in the present paper. | ||
