1. Inductie van een hypnotische staat Tijdens hypnotherapie wordt de cliënt geleid naar een staat van diepe ontspanning en gerichte aandacht. Deze staat lijkt op meditatie of “flow” en wordt gekenmerkt door trage hersengolven, met name theta‑golven (4–7,5 Hz), die geassocieerd zijn met ontspanning, emotie- en geheugensamenhang, en verhoogde suggestibiliteit. In deze toestand vermindert de…

İnsan Beynini Farklı Kılan Nedir?

İnsan Beynini Farklı Kılan Nedir? İnsan beynini, en yakın primat akrabalarımız da dahil olmak üzere diğer tüm hayvanlardan farklı kılan nedir? Yale araştırmacıları, dört primat türünün prefrontal korteksindeki hücre tiplerinin bir analizinde, türe özgü – özellikle de insana özgü – özellikleri belirlediler, çalışma 25 Ağustos’ta Science dergisinde rapor edildi. Ve bizi insan yapan şeyin bizi…

Suprimir a vingança: Como o cérebro atua no processo

Pesquisadores descobrem quais zonas cerebrais são ativadas pela raiva.

O desejo de vingança pode ser a consequência de um sentimento de raiva. Mas este é o caso no nível cerebral? O que acontece no cérebro humano quando sentimos a injustiça?

Para responder a essas perguntas, pesquisadores da Universidade de Genebra (UNIGE), na Suíça, desenvolveram um jogo econômico em que um participante é…

Magnetic Brain Stimulation Alters Negative Emotional Perceptions

Using magnetic stimulation outside the brain, a technique called repetitive transcranial magnetic stimulation (rTMS), researchers at University of Münster, Germany, show that, despite the use of inhibitory stimulation currently used to treat depression, excitatory stimulation better reduced a person's response to fearful images.

. – Amygdala is important for emotional (positive and negative) reactions.

 – Ventromedial prefrontal cortex: a critical hub for caregiving behaviors, morality, and decisionmaking, by combining cognitive and emotional processes necessary to guide social behavior. An area of the brain called the ventromedial prefrontal cortex has been found to be important for certain aspects of human morality. Patients who have damage to this brain region or who have had it removed also tend to experience less empathy, embarrassment, and guilt than people without damage to this region.

 – Dorsolateral prefrontal cortex plays an important role in self-control and intelligence.

 – Insula provides the foundation for being aware of our body feels. 

How the cortex assigns credit for causality

Say, for instance, you've forgotten which of your 10 usual passwords logs you into a favorite website. When you finally enter the right one, your brain should have a mechanism for noting which one led to that success.

Positioned on the brain's surface behind the top of the forehead, the dorsolateral prefrontal cortex (dPFC) is in a vulnerable place.

If some dPFC neurons have that function, Asaad and his colleagues reasoned, then they should have to behave in four specific ways during the task.

How the Cortex Assigns Credit for Causality

When you do something right, you can't learn anything from your success without a system in the brain for assigning credit to whatever action led to the desired outcome.
