This common sense leads to the perception that these effects are extensive to the weight of fruits, putamens, number of putamens per fruit, pulp weight, among others.
The physical characteristics analyzed were: total fruit weight (MTF); weight of the external mesocarp (MME); number of putamens per fruit (NP); total weight of putamens (MTP); mean weight of putamens (MMP); total pulp weight (MTPL) and average pulp weight (MMPL) - evaluated in grams.
As for the average weight (g) of putamens (MMP), Vera et al.
In addition, seven gross subcortical ROIs were rated: the anterior cingulate gyrus (BAs 25, 32, 33, and the anterior aspect of BA 24); the left and right insula; the left and right caudate nuclei; and the left and right putamens. Raters were blinded to patients' clinical data.
The two comparison group concentration decreases were in the left caudate and right putamen.
In addition, our finding of a right putamen deactivation in our comparison group during concentration may indicate a greater capacity for bringing their prefrontal cortices online.
O fruto caracteriza-se por ser drupoide, verde, com epicarpo coriaceo carnoso, contendo de um a quatro carocos (putamens ou pirenios) envolvidos por um mesocarpo amarelo-claro, endocarpo lenhoso espinhoso e sementes reniformes (ALMEIDA et al., 1998).
Pelo fato de ser uma especie nao domesticada, observa-se grande variacao entre matrizes para algumas caracteristicas fisicas nos frutos, como tamanho, coloracao, numero de putamens por fruto, peso de putamens e de suas respectivas polpas.
Seu fruto, popularmente conhecido como pequi, e uma drupa contendo de um a quatro putamens em seu interior (CORREA et al., 2008).
A caracterizacao biometrica de frutos e putamens pode fornecer subsidios sobre a importancia da associacao da especie estudada com os fatores ambientais (CARDOSO; LOMONACO, 2003).
In fact, those researchers have pinpointed the brain's disgustometer, which they say resides in the insula and putamen. They reached this conclusion after studying a 25-year-old man with a lesion in those regions and finding that he had trouble recognizing facial expressions and other nonverbal signs of disgust, such as retching.
