leo:
En este estudio realizado en la Universidad de Edimburgo se apreció
que, cuando las personas hacían una pequeña pausa después de una
tarea de aprendizaje (como aprender una cadena de números), podían
recordarlos mejor, en comparación con quienes no tuvieron la
posibilidad de tomar un descanso que consolidara el aprendizaje.
Para verificar si esta teoría se podía aplicar realmente al recuerdo
de las historias, los investigadores fueron más allá de las cadenas
de números y le pidieron a los participantes que leyesen una historia.
Siete días después, debían narrar todos los detalles que recordasen.
El punto clave fue que algunos leyeron la historia
ininterrumpidamente y otros tomaron pausas de 10 minutos.
Una vez más, aquellos que habían leído la historia haciendo pausas,
mostraban un recuerdo mejor. Lo más sorprendente de todo es que este
recuerdo se podía equiparar con la cantidad de detalles que brindaban
las personas que habían leído la historia de un tirón, tan solo 15 o
30 minutos después.
Nootrópicos (smartdrugs, drogas inteligentes, potenciadores cognitivos) son sustancias artificiales (medicamentos como piracetam, hydergina, citicolina, fosfatidilserina, vinpocetina, etc.) o naturales (suplementos nutricionales, vitaminas, aminoácidos, hormonas, hierbas, etc. como vitaminas B, piroglutamato, Gingko Biloba, fenilalanina, DHEA, pregnenolona, etc.) que se utilizan para mejorar la capacidad cognitiva (memoria, atención, etc.) en personas con trastornos o normales.

Mantener niveles de glucosa para sostener la motivación
n the researchers' discussion of the results, they said, "At its core,
self-regulatory change involves overriding one response in order to
enable a different response. The stronger the initial response or
impulse, the more difficult the self-control task will be—and, we
would assume, the greater amount of energy in the form of blood
glucose the system would have to expend in order to succeed."1 We
agree with the researchers that glucose is likely to provide only a
short-term help in counteracting the performance impairment resulting
from prior effortful self-control because there will be counteracting
metabolic factors (such as the need to release insulin in order to be
able to use the glucose for energy) that prevent maintaining a high
level of energy from a given amount of glucose for very long. It
would be like trying to maintain the energy increasing effects of
caffeine by drinking a cup of coffee again and again. That doesn't
work for very long because the factors that provide the lift from
caffeine, such as the release of noradrenaline, are depleted after a
while.
***In fact, you can extend the energy enhancing effect of caffeine by
taking nutrients the brain can use to make more noradrenaline, such
as the amino acids phenylalanine or tyrosine. In the case of glucose,
we would expect that taking nutrients along with glucose that improve
insulin sensitivity, such as chocolate, black tea, or cinnamon, might
extend the length of time you could extract energy from a given
amount of glucose.***
