Resolving the active versus passive conundrum for head direction cells
2014, NeuroscienceCitation Excerpt :The firing rate sensitivity of NPH neurons at a constant head velocity generally decreases as the frequency, or number of changes in the direction of the head rotation, increases during smooth or low-frequency head movements. However, the NPH neurons display the opposite – increased firing rates with increasing rotational frequency when the head movements contain more perturbations, or are in a range of higher frequencies, which would be seen during locomotion (Lannou et al., 1984; Kaufman et al., 2000). There is currently little information about NPH neuron activity in relation to changes in rotational velocity for head movements of similar frequency (smooth vs. interrupted).
Nucleus prepositus
2006, Progress in Brain ResearchCitation Excerpt :The visual inputs probably play an important prominent role in the transmission of visual optokinetic signals to vestibular neurons and VOR pathways (Cazin et al., 1982, 1984; Cheron et al., 1986; Kaneko, 1999). Detailed descriptions of the eye-movement-related responses of PH neurons have been provided in rodents (Lannou et al., 1984; Kaufman et al., 2000), cats (Lopez-Barneo et al., 1982; Escudero and Delgado-Garcia, 1988; Kitama et al., 1995), and primates (McFarland and Fuchs, 1992; Cullen et al., 1993; Sylvestre et al., 2003). The single-unit recordings were obtained usually from the rostral parts of the prepositus nucleus.
Retrograde-labeling of pretecto-vestibular pathways in cats
2003, Auris Nasus LarynxDoes the vestibular system contribute to head direction cell activity in the rat?
2002, Physiology and BehaviorCitation Excerpt :Conventional neuroanatomical techniques have demonstrated a large input to LMN from the dorsal tegmental nucleus of Gudden (DTN) [26–28]. The DTN receives inputs from prepositus hypoglossi (PH) [26,29,30], a region of the caudal medulla adjacent to the vestibular nuclei that processes vestibular signals related to horizontal head velocity [31,32]. Thus, vestibular signals could potentially be transmitted from the vestibular nuclei to PH, and then to DTN, and then to HDC in LMN, ADN, and PoS.
