Over the weekend, I dropped by to say Hi to my grandma Carolina, the Wise Neuroscientist every family should have. She always helps me out.

The conversation went so well, that we are adding it to our Neuroscience Interview Series on learning and “brain gyms”.

The word “clock” is a metaphor, and the concept tries to exclude direct responses to the environment. Make sure to understand this properly, otherwise Bora suggests explaining it to you this way: “If I give you an electroshock every two hours, you will exhibit a 2-hour cycle of convulsions…but that’s not a biological clock”.
Alvaro: Crystal clear. Hmmm, I am thinking of nothing in particular right now, my mind wanders, like a river stream…what may be happening in my brain?
Carolina: Nothing special, as The Neurocritic seems to argue in his series Default Mode or Detritus?, , and . Don’t be easily seduced by sexy neuroimaging into believing that “default” constitutes some kind of baseline.
Alvaro: I wouldn’t dare do so, by no means. Read the rest of this entry »
