Sensorimotor development

The team is interested in determining the sequence of sensory maturation at both behavioural and brain levels. Brain investigations are mainly based on morphometry, localisation of Heavy Neurofilament, HNf, quantification of monoamines, mainly 5HT, and their receptors. The effect of chronic embryonic stimulation with predator cues (a potential stressor) on the brain and behaviour of hatchlings are studied. Since laterality in young cuttlefish is affected by prior embryotic exposure to predator odors. Adaptive determinants of developmental changes will be investigated further. Amongst others, we assess the efficiency of defensive and predatory behaviour of differently-lateralized juveniles and determine the functional specialization of each half-brain.
