I love this kind of research because it shows how there's an affective undercurrent to essentially every part of our lives. This is formalized in microvalence theory (Lebrecht et al., 2012), which posits that all objects, even ordinary ones, are imbued with valence (e.g., explaining why you prefer one chair over another). As far as positive geometric ...

Quoting my thesis: CNS Dopamine/DA projections primarily emerge from two subcortical basal ganglia nuclei in the brain stem, travelling along three major pathways (Purves et al., 2004). The nigrostriatal pathway, connecting the substantia nigra and the striatum, is mainly implicated in higher motor control. The mesolimbic pathway contains DA ...

Parts of the brain affected by dopamine Dopamine exerts different effects in different regions and pathways throughout the brain. In the mesolimbic pathway, dopamine is believed to be involved in motivation and addiction due to the feelings of reward and pleasure associated with dopamine release here. In the mesocortical pathway, dopamine is linked to ...

Most brain-machine interfaces involving movement would be based on activity in primary motor cortex, which, as you said, is near the surface. Right next to that are is primary somatosensory cortex, which is the first cortical area where touch information is processed. It is also near the surface. Most of the neocortex is going to be near the surface, with ...

Actually it's a bit complicated but in simple terms : Neurotransmitters are stored in a synapse in synaptic vesicles, clustered beneath the membrane in the axon terminal located at the presynaptic side of the synapse. Neurotransmitters are released into and diffused across the synaptic cleft, where they bind to specific receptors in the membrane on the ...

No, unlike norepinephrine and serotonin, dopamine's pathway is limited.actually it affects two part of cognition, reward and motor functions. As part of the reward pathway, dopamine is manufactured in nerve cell bodies located within the ventral tegmental area (VTA) and is released in the nucleus accumbens and the prefrontal cortex. The motor functions of ...

The first question that should be asked is, do you mean cognitive ability or IQ? They are intertwined, but different. Unfortunately, I can not comment. I'm going to answer based on the question in the title. Yes. Walter Mischels work on self-control indicates that anger, a "hot" emotion led by the amygdala in the limbic system, will provoke more immediate ...

I think it's a primal need that is built in via natural selection. Those that had attachments to places and things outpased those who didn't. The affection a child shows for a favorite toy or a teenager shows for a favorite pair of shoes. Also, when a possession has been won over a great hardship, it has intrinsic meaning. This has a social and mental ...
