We are all cyborgs now

when you have no external input, that is a time when there is a creation of self, when you can do long-term planning, when you can try and figure out who you really are.
kids today, they’re not going to be dealing with this downtime

Social media hurts your short-term memory.
Erik Fransen is a globally recognized expert on short-term memory at Stockholm’s Kungliga Tekniska Högskolan (Royal Institute of Technology) and is affiliated with the Stockholm Brain Institute.
His research indicates that overuse of social media hurts the brain in two ways:

Escaping the here and now: Evidence for a role of the default mode network in perceptually decoupled thought
NeuroImage, 2013, 69, 120-125.

Cognition that is not based on perception can lead to at least two different outcomes.
In some situations, cognition that is independent of perception can allow actions to be selected other than those prescribed by immediate perceptual input.
In others, cognition can be independent of perception and unrelated to the current behavioral goal allowing thoughts to develop that are largely independent of the actions involved in an external task.
The default mode network (DMN) has been implicated in both of these kinds of perceptually decoupled thought.
The current experiment used functional magnetic resonance imaging to explore whether a common region of this network was co-activated by both of these states.
Both the medial pre-frontal cortex and the posterior cingulate – two major hubs of the DMN – showed greater activity when (i) actions that did not depend upon immediate perceptual input were faster and
(ii) when actions based on perceptual input were slower.
Together these data suggest that the DMN is important in cognition that is independent from perceptual input regardless of whether such thoughts result in action, or, instead compete with the behavioral goals of the moment.

Neuroscience: Idle minds
Neuroscientists are trying to work out why the brain does so much when it seems to be doing nothing at all.

13:00 Impact of distraction on long-term memory (3 scenarios: eyes shut, looking at gray screen or busy visual picture)
14:23 how exquisite sensitive our memory is, even to the normal environmental stimulation that we can not escape
15:29 prefrontal cortex
15:56 In your visual cortex there is only room for 6 objects or even less at a time, depending on how complex they are

17:23: Multitasking: Costs: – Time delays in switching – Impact on task performance (you don’t do 2 things as well as you do 1 thing)
17:50 Why do we multitask (some sources are anecdotal): – Flexibility – Fresh perspective – Increased variety – Enables us to use downtime productively – More fun
19:10 So, what can be done? – Change our behavior – Change our brains 20:05 Change our behavior: Establish rules – Important tasks demanding high quality should be given singular attention (e.g., quit mail, turn off phone, shut the door). – Boring, easier, less critical tasks are better candidates for multitasking
