In a cortical circuit, precise STPs thus reflect the interaction between internally generated activity and sensory information.
The spatially dissociated firing sequences suggest that hippocampal neurons in the transgenic mice are not primarily driven by external space but by internally generated brain activities.
Within sharp wave/ripples (SWRs) in local field potentials (LFPs) during slow-wave sleep or periods of awake immobility, internally generated place cell activity sequences are often reactivated in a temporally compressed manner (Wilson and McNaughton, 1994; Foster and Wilson, 2006; O'Neill et al., 2006; Diba and Buzsáki, 2007; Karlsson and Frank, 2009; Gupta et al., 2010).
The bright terrain in the grooves probably formed during a period of tectonic activity in which internally generated stresses disrupted and fractured the crust.
Local field potential (LFP) recordings from the human subthalamic nucleus (STN) demonstrate population activity that precedes internally generated and externally paced voluntary movement (Cassidy et al., 2002; Priori et al., 2002; Paradiso et al., 2003; Kuhn et al., 2004; Alegre et al., 2005; Doyle et al., 2005; Alonso-Frech et al., 2006; Devos & Defebvre, 2006; Androulidakis et al., 2007).
Activity in the insula can relate to self-induced or internally generated emotions, and recalled emotions can activate the insula [54], [55].
For example, motor activity, sensory consequences and the extent to which the former predicts the latter, may be invoked to account for the sense that a particular action was internally generated.
Rather than viewing the spatiotemporal sequence of activity which produces movement as internally generated by cortical circuits in a feedforward manner [Churchland et al., 2012; Shenoy et al., 2013], such a view would extend the "dynamical machine" [Shenoy et al., 2013] responsible for movement to include afferent feedback from the periphery.
There is a hierarchical organization of the stress-responsive neurocircuitries on the PVN, which is able to integrate information from multiple limbic sources with internally generated and peripherally sensed information, thereby tuning the relative activity of the adrenal cortex.
Close observation of internal experience was defined as awareness of internally generated stimuli, such as sensations, cognition, and emotions.
