The characteristics of anxiety behavior and reproduction of a conditioned passive avoidance reflex acquired in response to a single combination with an unconditioned aversive stimulus were studied in NISAG rats with inherited stress-sensitive arterial hypertension and spontaneously hypertensive SHR rats. SHR rats were characterized by hyperactive behavior, very low levels of anxiety, and poor reproduction of the conditioned reflex as compared with NISAG and control Wistar and WAG rats. Intermediate-anxiety NISAG rats showed no difficulties in acquiring and subsequently retaining the conditioned reflex. These differences in the ability to undergo single-combination learning in rats with different forms of hypertension suggest that memory processes are independent of elevated arterial blood pressure. The effects of the genetic characteristics of behavior and emotional status of these animals on memory are discussed.

Effects of cypermethrin exposure on learning and memory functions and anxiety-like behavior in rats.

Background: Cypermethrin (CYP), a synthetic pyrethroid widely used to control plant pests, has been associated with various diseases in humans exposed to pesticides, either directly or indirectly. This study aimed to examine the effects of CYP on learning and memory functions, as well as anxiety-like behavior.
Methods: Forty male Wistar rats (8 weeks old) were randomly assigned to 4 groups: The first group served as the control, while the other three groups received different doses of CYP (5, 20, and 80 mg/kg) via gavage once daily for one month.

The increasing demand for energy in cooling systems due to global warming presents a significant challenge. Conventional air-conditioning methods exacerbate climate change by contributing to heightened carbon emissions. Glass facades, renowned in modern architecture for their versatility and aesthetic appeal, inadvertently trap solar radiation, resulting in heat buildup and the greenhouse effect.

: We assessed the influence of long-term injection of magnoflorine (MAG) on memory acquisition in mice for the first time. : This isoquinoline alkaloid that belongs to the aporphines was isolated from the roots of by centrifugal partition chromatography (CPC) using a biphasic solvent system composed of chloroform: methanol: water in the ratio 4:3:3 (//) with 20 mM of hydrochloric acid and triethylamine, within 64 min. : Our results indicated that long-term injection of MAG 20 mg/kg dose improve the long-term memory acquisition in mice that were evaluated in the passive avoidance (PA) test with no toxicity records.

Recent studies suggest that calcitonin gene-related peptide (CGRP) neurons in the parabrachial nucleus (PBN) represent aversive information and signal a general alarm to the forebrain. If CGRP neurons serve as a true general alarm, their activation would modulate both passive nad active defensive behaviors depending on the magnitude and context of the threat. However, most prior research has focused on the role of CGRP neurons in passive freezing responses, with limited exploration of their involvement in active defensive behaviors.
