People are definitely way more excited about neurogenesis in adulthood than in early development. Which is fine. But the emphasis on adult neurogenesis has exposed some gaps in our understanding of the developmental process and so we have embarked on a study to compare neurons born are these different stages…
Everybody knows what the hippocampus is for: memory. And…maybe something about anxiety or depression? Yes – over the last 10 years or so many studies have been published showing that the hippocampus has these two roles and that the mnemonic and emotional functions of the hippocampus are associated with its…
And now for a journey outside (rostral, to be precise) of my comfort zone. These three pictures show new neurons in the mouse olfactory bulb at successively greater magnifications. Probably inspired by the science magazine I read as a kid that would show high mag photos of everyday objects (with corresponding…
Dendrites are the extensions of neurons that receive incoming information. Neurons have primary dendrites that further split off into secondary and tertiary dendritic branches. On each of these branches are thousands of synaptic connections with axons of neurons carrying incoming information. The result is a dendritic tree that is capable of receiving…
Most studies of adult neurogenesis are concerned with neuronal age. Or at least they should be. This is because new neurons develop from a stage where they have no excitatory synapses to one where they have many. If we assume the traditional view that information is stored at excitatory synaptic…
