Key parts of regeneration are to know when damage has occurred and to detect that correct shape has been restored; thus, measurement of specific properties (from molecular signals to overall shape or size) is a key component. From a cognitive perspective, sensory processing and perception imply that the system is capable of detecting and converting internal or external sensory information (mediated by some specific physical signal) into a perceptual quality-bearing salient information. The final perceptual representation will contain not only measurable data (such as timing, space, and quantity) but also the necessary information for initiating a circuit (in case the information is important enough to make a decision), which leads to an action for reaching or maintaining current goals (Mechelli et al. 2004, Kiebel et al. 2009, Hogendoorn 2015). For the system, the stimulus is more than the sum of its individual physical characteristics; a stimulus has a behavioral meaning in a relevant context (Kim and Biederman 2011, Maren et al. 2013). It should be noted that this aspect of context permeates the molecular biology of pattern regulation, where the same molecules (e.g., Wnt-5, sonic hedgehog, and calcium) are used in many different structures for many different outcomes, revealing the need for informational context in cells’ interpretation of chemical or physical stimuli.

– Atypical sensory processing (i.e., either enhanced and decreased), which may occur in different sensory modalities (see Belmonte & Yurgelin-Todd, 2003, Kanakri, 2012, Kern et al., 2007, Baranek et al., 2007 Lockner et al., 2008). Empirical evidence for atypical processing of visual and auditory information is the most established (e.g., see Mottron et al., 2006, Bertone et al., 2005; Belmonte & Yurgelun-Todd, 2003).

See Figure 4 for a visualisation of the time windows and the significant ERP components (ie contralateral negativity and LDAP) in response to the cue. The main effect of hemisphere was not significant in the early time window that includes an early positive component indicating sensory processing of the arrow cues (50–100 ms, F(1,16) = 0.71, p = .41, ηρ² = 0.04). A significant main effect of hemisphere (ipsi vs. contralateral) confirmed a contralateral negativity (150–200 ms, F(1,16) = 7.49, p = .015, ηρ² = 0.32) and a contralateral positivity (LDAP: 500–650 ms, F(1,16) = 40.25, p < 0.001, ηρ² = 0.72), indicating interpretation of cue direction and directing of attention. There was no significant effect of WM load on these components.
