Attention Systems
Attention, which amplifies the information we focus on.
**During every second our brain evaluates what inputs are important to us. It just allocates our resources. **
With conscious attention, the discharges of the sensory and conceptual neurons that code for an object are massively amplified and prolonged, and their messages propagate into the prefrontal cortex, where whole populations of neurons ignite and fire for a long time, well beyond the original duration of the image. Such a ==strong surge of neural firing is exactly what synapses need in order to change their strength.==
(p.149)
Three major attention systems:
- ==Alerting==, which indicates when to attend, and adapts our level of vigilance. ⇒ Alerting Systems, The Awakening of the Brain
- Orienting, which signals what to attend to, and amplifies any object of interest. ⇒ Orienting, the Brain’s Filter
- ==Executive attention==, which decides how to process the attended information, selects the processes that are relevant to a given task, and controls their execution. ⇒ Executive Control, The Brain’s Switchboard
