A neuroanatomia das emoções

 

 

 

 

 

 

 

Para começar com a descrição da neuroanatomia das emoções, Paul Broca foi responsável por cunhar o termo sistema límbico, usando-o pela primeira vez em 1878. Mas foi só depois, em 1930, que James Papez batizou definitivamente as estruturas envolvidas com o nome de sistema límbico (SL), postulando que o mesmo participa do circuito neural da expressão emocional (Kolb e Whishaw, 2003).

Toward a New Frontier in Human Intelligence: The Person-Centered Approach

When it comes to intelligence, we all have bad days. Heck, we even have many bad moments, such as when we forget our car keys, forget a friend’s name, or bomb an important test that we’ve taken a day after staying up all night worrying about it. Truth is, none of us– including the world’s smartest human– is perfectly consistent in our cognitive functioning. Sometimes we are at our very best and feel like our brain is on fire, and at other times, we don’t even recognize ourselves.

All of this sounds so obvious, but surprisingly the field of human intelligence has not had much to say on the topic. For over the past 120 years, the field has shed far more light on how we differ from each other in our patterns of cognitive functioning than how we each differ within ourselves over time.

This is curious considering that a person-centered approach has proved fruitful in other fields, such as medicine and neuroscience. Even within the study of human behavior there has been progress, from looking at how individual emotions fluctuate over time, to how individual personality traits such as introversion and openness to new experiences and even our morality fluctuates throughout the course of the day. It has become increasingly clear that the results from the traditional individual differences paradigm– where we compare people to each other– often does not apply at the person-specific level.

Air pollution linked to childhood anxiety

 

Exposure to air pollution is a well-established global health problem associated with complications for people with asthma and respiratory disease, as well as heart conditions and an increased risk of stroke, and according to the World Health Organization, is responsible for millions of deaths annually. Emerging evidence now suggests that air pollution may also impact the metabolic and neurological development of children.

A new study from researchers at the University of Cincinnati and Cincinnati Children’s Hospital Medical Center looks at the correlation between exposure to traffic-related air pollution (TRAP) and childhood anxiety, by looking at the altered neurochemistry in pre-adolescents.
