The IAS region is characterized by climate features of unique nature, one of them is the Mid-Summer Drought (MSD), “veranillo” or “canícula” in Spanish, an atmospheric attribute rarely observed in tropical regions. On ...
Observed Changes (1970-1999) in Extreme Hydroclimatic Events in Central America
Previous studies have shown that most of Central America has been experiencing warming trends during the last 30-50 years, while precipitation annual totals have not changed much. Warming alone can exacerbate the effects ...
(Hydro)climatological studies of climate change and variability in Central America
This is the presentation of Hugo Hidalgo at the CORDEX Central America and South America Training Workshop on Downscaling Techniques, in La Paz, Bolivia, June 25 to 27, 2018.
Age, experience, and neurobehavioral domain: dissociable effects of environmental enrichment and social isolation on brain and behavior in adult and aged rats
In rats, environmental enrichment (EE) is a form of physical-social stimulation used for modeling the impact of optimal developmental conditions on animal’s phenotype. When implemented during early life, EE improves animal’s ...
Habituation and spatial memory in the context of emotional regulation: Behavioral and genetic mechanisms underlying context information-processing and de-arousal grooming
Habituation is the ability to passively reduce a response after repeated or prolonged exposures to a particular stimulus. From a cognitive perspective, habituation is a basic, information-gating process that contributes ...
Muscarinic and glutamatergic regulation of self-grooming behavior and ultrasonic vocalizations in the context of open-field habituation in rats
We tested whether pharmacological impairment of OF-habituation after the administration (i.p.) of scopolamine (SCP; muscarinic antagonist) or MK-801 (MK; NMDA antagonist) was able to disrupt or alter grooming syntaxes. ...
