is short term memory capacity 7 2 really predicted by theta to gamma cycle Length Ratio
Behavioural Brain Research, 2021Co-Authors: Kristýna Maleninska, Kateřina Sulcova, Veronika Rudolfova, Vlastimil Koudelka, Martin Brunovský, Jiři Horacek, Tereza NekovařovaAbstract:Several studies suggest that EEG parameters, reflecting top-down processes in the brain, may predict cognitive performance, e.g. short-term memory (STM) capacity. According to Lisman and Idart's model, STM capacity is predicted by theta and gamma EEG waves and their Ratio. This model suggests that the more periods of gamma band waves fit into one period of theta band waves, the more information can be stored. We replicated the study of Kaminski et al. (2011), which recorded spontaneous EEG activity and measured verbal STM capacity with a modified digit span task from the Wechsler battery. Our study included more subjects and two EEG recording sessions. We discuss possible limits of EEG correlates of STM capacity as no correlation was found between theta/gamma Ratio and performance in digit span task. EEG parameters were not stable across the two measurements.

Early-to-Mid Gestation Fetal Testosterone Increases Right Hand 2D:4D Finger Length Ratio in Polycystic Ovary Syndrome-Like Monkeys
2016Co-Authors: Andrew D. Abbott, Ricki J. Colman, Ross Tiefenthaler, Daniel A. Dumesic, David H. AbbottAbstract:A smaller Length Ratio for the second relative to the fourth finger (2D:4D) is repeatedly associated with fetal male-typical testosterone (T) and is implicated as a biomarker for a variety of traits and susceptibility to a number of diseases, but no experimental human studies have been performed. The present study utilizes the rhesus monkey, a close relative of humans, and employs discrete gestational exposure of female monkeys to fetal male-typical T levels for 15–35 days during early-to-mid (40–76 days; n = 7) or late (94–139 days; n = 7) gestation (term: 165 days) by daily subcutaneous injection of their dams with 10 mg T propionate. Such gestational exposures are known to enhance male-typical behavior. In this study, compared to control females (n = 19), only early-to-mid gestation T exposure virilizes female external genitalia while increasing 2D:4D Ratio in the right hand (RH) by male-like elongation of RH2D. RH2D Length and 2D:4D positively correlate with androgen-dependent anogenital distance (AG), and RH2D and AG positively correlate with duRation of early-to-mid gestation T exposure. Male monkeys (n = 9) exhibit a sexually dimorphic 2D:4D in the right foot, but this trait is not emulated by early-to-mid or late gestation T exposed females. X-ray determined phalanx measurements indicate elongated finger and toe phalanx Length in males, but no other phalanx-related differences. Discrete T exposure during early-to-mid gestation in female rhesus monkeys thus appears to increase RH2D:4D through right-side biased, non-skeletal tissue growth. As variation in timing and duRation of gestational T exposure alter male-like dimensions of RH2D independently o

Early-to-mid gestation fetal testosterone increases right hand 2D:4D finger Length Ratio in polycystic ovary syndrome-like monkeys.
PloS one, 2012Co-Authors: Andrew D. Abbott, Ricki J. Colman, Ross Tiefenthaler, Daniel A. Dumesic, David H. AbbottAbstract:A smaller Length Ratio for the second relative to the fourth finger (2D∶4D) is repeatedly associated with fetal male-typical testosterone (T) and is implicated as a biomarker for a variety of traits and susceptibility to a number of diseases, but no experimental human studies have been performed.

Discrete T exposure during early-to-mid gestation in female rhesus monkeys thus appears to increase RH2D∶4D through right-side biased, non-skeletal tissue growth. As variation in timing and duRation of gestational T exposure alter male-like dimensions of RH2D independently of RH4D, postnatal RH2D∶4D provides a complex biomarker for fetal T exposure.
