How neuronal migration and outgrowth shape network architecture
Neurons are not randomly arranged in the human brain. In the cortex, they are organized in interconnected clusters with high intrinsic connectivity. This modular connectivity structure, in which clusters eventually serve as functional units, is formed in early phases of development. The underlying self-organization process is regulated by neuronal activity but the detailed mechanisms are still poorly understood. Based on in vitro studies and computational modeling, neuroscientists have now made an important contribution to the understanding of brain networks and their development: in their current study, they show how neuronal outgrowth and migration interact in shaping network architecture and the degree of modularity in mature networks.
Read moreLow intelligence linked to suicide risk later in life
People with low scores on intelligence tests in adolescence run a higher risk of suicide and suicide attempt later in life. That is according to a study that followed almost 50,000 Swedish men from the 1970s until recently.
Read moreDog ownership associated with longer life, especially among heart attack and stroke survivors
Dog ownership was associated with a 33% lower risk of early death for heart attack survivors living alone and 27% reduced risk of early death for stroke survivors living alone, compared to people who did not own a dog. Dog ownership was associated with a 24% reduced risk of all-cause mortality and a 31% lower risk of death by heart attack or stroke compared to non-owners.
Analysis of US labor data suggests 'reskilling' workers for a 'feeling economy'
A study of US labor data suggests AI is already taking 'thinking economy' jobs from humans, and this trend will grow in the future. This will push more people into 'feeling economy' jobs that require things like interpersonal relationship skills and emotional intelligence.
Read moreCTE risk, severity increases with years playing American football
The risk and severity of developing chronic traumatic encephalopathy (CTE) increases with the number of years playing American football according to a new study. These findings reaffirm the relationship between playing tackle football and CTE, and for the first time quantify the strength of that relationship.

Criticality is truly a set point, and not a mere inevitability. New research confirms this long-standing prediction in the brains of freely behaving animals.

Experiments showed that the brain's parahippocampal place area is involved in recognizing a particular kind of place, while the brain's retrosplenial complex is involved in mentally mapping the locations of particular places.
