G1/S restriction point coordinates phasic gene expression and cell differentiation
Somatic cells display phasic gene expression with compartmentalized gene expression during the cell cycle, while pluripotent cells lack phasic expression. Here, the authors describe a pathway linking microRNA regulation of the G1/S restriction point with

Brainstem circuitry regulating phasic activation of trigeminal motoneurons during REM sleep. [PDF]
Rapid eye movement sleep (REMS) is characterized by activation of the cortical and hippocampal electroencephalogram (EEG) and atonia of non-respiratory muscles with superimposed phasic activity or twitching, particularly of cranial muscles such as those ...

Phasic firing in dopaminergic neurons is sufficient for behavioral conditioning. [PDF]
Natural rewards and drugs of abuse can alter dopamine signaling, and ventral tegmental area (VTA) dopaminergic neurons are known to fire action potentials tonically or phasically under different behavioral conditions.

Cholinergic neurons of the pedunculopontine nucleus (PPN) are most active during the waking state. Their activation is deemed to cause a switch in the global brain activity from sleep to wakefulness, while their sustained discharge may contribute to ...

Phasic alertness and cue informativeness
Phasic alertness is referred to as a short-lived increase in attentional intensity that is evoked by non-specific external stimuli (Sturm & Wilmes, 2001).

Slope-based stochastic resonance: how noise enables phasic neurons to encode slow signals. [PDF]
Fundamental properties of phasic firing neurons are usually characterized in a noise-free condition. In the absence of noise, phasic neurons exhibit Class 3 excitability, which is a lack of repetitive firing to steady current injections. For time-varying
