Disturbances in the neuronal activity of the hippocampal CA2 subregion have been shown to result in impaired social memory in rodents. However, the current assessment of behavioural role of CA2 within the circuit of cognition relies on classical tests, presenting only a snapshot of the behaviour of subjects. As both clinical and preclinical data have revealed a relevance for CA2 in psychiatric disorders such as schizophrenia, it is crucial to uncover the effects of CA2 E/I imbalance in more natural social environments over longer periods of time. Furthermore, gaining a deeper understanding of

The pupillary light response (PLR) controls pupil’s aperture according to the environmental luminosity, maximizing imaging efficiency while minimizing retinal damage. The PLR is present in most vertebrates, and two mechanisms have been described to achieve it: 1) In almost all vertebrate groups, it’s mediated by the Edinger–Westphal nucleus via the ciliary ganglion. 2) Some vertebrates, such as amphibia, fish, reptile and several mammals additionally show an iris-intrinsic mechanism evoked by the photoreceptor melanopsin, present in the sphincter pupillae muscle, whose activation produces musc
