1. Introduction The average adult human brain (1,350 g) contains approximately 86.1 (±8.1) billion neurons [Azevedo, Carvalho, Grinberg, Farfel, Ferretti, Leite, Filho, Lent & Herculano-Houzel, 2009; Pakkenberg, Pelvig, Marner, Bundgaard, Gundersen, Nyengaard & Regeur, 2003], and the number of non-neuronal … Continue reading
1. Introduction. Since the Big Bang, the age of the observable universe is estimated to be 13.75 (±0.11) billion years [see Larson, Dunkley, Hinshaw et al., 2010] and the age of our planet, Earth, has been consistently estimated to be … Continue reading
During my graduate work at San Diego State University (MA, Psychology ’11) I spent the bulk of my time developing behavioral models to study healthy aging; more specifically, I used existing/published paradigms using hippocampal lesioned rodents to test some of … Continue reading
As previously mentioned, the deficits associated with the aging brain can be very difficult to generalize. Even within the distribution of healthy aging (i.e., aging without any neuropathologies such as Alzheimer’s disease or Lewy body dementia) there is a great … Continue reading
Natural exploration is of particular importance when considering animal behavior, as it is the means by which animals gather information about their environment, discover available resources, and identify potential threats. Furthermore, a number of studies have shown that tasks utilizing … Continue reading
