Responding to Violence, Suicide, Psychosis and Trauma

Reduced thalamic volume in men with antisocial personality disorder or schizophrenia and a history of serious violence and childhood abuse

This is interesting because it lends further support to the idea that the thalamus is implicated, through faulty sensory filtering, both in the development of psychotic symptoms – particularly hallucinations – and also it’s relationship with violent behaviour.

Humans have “Super Spidey Sense” for Danger

The Instant Aggression Model largely depends on the idea that people can sense danger before they are consciously aware of it. This is usually referred to as intuition or a gut reaction. The explanation lies in role played in the brain by the thalamus which filters all incoming sensory data – channeling important data up to the pre-frontal cortex where it can be thought about, but channeling dangerous data directly to the amygdala which processes emotion and activates the body before thought takes place. Interestingly this idea has received further support in a study widely reported on the internet suggesting that people do indeed have a “Spiderman” like ability to sense danger before it happens. Actually, the research is not quite so clear as the headlines, but it makes an interesting read none-the-less:
