Neurons in human dorsal motor cortex, an area involved in controlling arm and hand movements, are also active – and show similar ensemble dynamics – during speaking.
Upon injury, the regeneration of the adult axolotl brain rebuilds neuronal diversity, but alters the original long-distance circuitry and tissue architecture.
The finding that fly maggots, equipped with only 10,000 neurons, process reinforcement not only by value but also by specific quality reveals a basic operating principle of brains and challenges current models of memory organization.
A computational tool developed to construct three-dimensional anatomical atlases from two-dimensional data generates volumetrically complete and aligned atlases for all stages of development in the Allen Developing Mouse Brain Atlas.
Cross-species alignment based on cortical myelin content can dissociate cortical expansion and relocation from changes in connectivity profiles in the temporal lobe of higher primates.
The exceptionally large size of the human brain is the result of accelerating evolution towards larger brains in hominins, but is not the product of neocortical expansion.
