Symposia
Human-specific cortical microcircuit function and structure (Karri Lämsä)
Human-specific cortical microcircuit function and structure (Karri Lämsä) 2017-09-22 - 15:00-17:00
Venue: Conference Room F08
Neocortical and hippocampal microcircuit features specifically found in humans and not in rodents, may be required to understand our brain function in health and disease. The symposium brings together experts from laboratories in Europe and overseas to give an updated picture of this timely and expanding research field.

SUMMARY

An increasing number of scientific studies support the idea that evolution has produced functional and structural specializations in the human neocortical and hippocampal microcircuits that do not appear in rodents. However, the vast majority of current cellular neuroscience research, aiming to ultimately understand the human brain function in health and disease, is carried out in model animals such as mice and rats. The microcircuit level specializations evolved in the human phylogeny may be crucial for the specific function of the human brain including abstract mental abilities and capacity of the cortex to perform higher cognitive functions. In addition, human-specific microcircuit features may be substrates for pathological processes resulting in neurological and neuropsychiatric dysfunctions that a mankind as a species is vulnerable to. However, specific features of the human neocortical and hippocampal microcircuits are still poorly known. Although mammalian cortex is evolutionarily conserved, differences occur between species. The topic is gaining increased attention worldwide, and many laboratories in Europe and overseas have initiated investigation of the human and rodent cortical microcircuits in parallel. The results have revealed various differences between our cortical microcircuits and the rodents. In addition to experts in physiological, anatomical or molecular biology research, the results are of general interest for neuroscientists in all fields.
