Jul 12, 2019 · Birds are extremely interesting animals for studying the neurobiological basis of cognition and its evolution. They include species that are highly social and show high cognitive capabilities. Moreover, birds rely more on visual and auditory cues than on olfaction for social behavior and cognition, just like primates. In primates, there are two major brain networks associated to sociality: 1. Nov 10, 2011 · The generation of individual neuron types in the nervous system is a multistep process whose endpoint is the expression of neuron type–specific batteries of terminal differentiation genes that determine the functional properties of a neuron. This review focuses on the regulatory mechanisms that are involved in controlling the terminally differentiated state of a neuron. I review several case. Jul 29, 2013 · Placode progenitors generate major components of sense organs. Lleras-Forero et al. show that neuropeptides control early placode development: mesendoderm-derived somatostatin promotes ectodermal nociceptin expression. Together, both peptides regulate Pax6 in lens and olfactory progenitors. Consequently, loss of somatostatin and nociceptin signaling leads to severe reduction of. Dec 04, 2019 · Here, we review evidence from evolutionary, developmental, and regenerative biology suggesting a deeper, ancestral function of both pre-neural and neural cell-cell communication systems: the long-distance coordination of cell division and differentiation required to.
The development of sexual orientation is a far from complete subject. While neuroscience has made advancements shedding light on the mechanisms and relationships between the human brain and sexual orientation, much more further research should be conducted. Areas for future research include. A common theme running through these examples is that evolution, as well as brain development, tends to be very conservative, typically extending, reappropriating, or modifying extant neurobiological mechanisms rather than engineering wholly new, dedicated mechanisms e.g., modules for each new challenge that the environment throws an organism.
