From synaptic transmission to cognition: An intermediary role for dendritic spines

Abstract

This work presents a complete navigation architecture for an autonomous aerial robot. The proposed scheme consist of: i) a low-level controller for establishing the attitude and position of the vehicle, ii) a Simultaneous Localization and Mapping (SLAM) system, based in bearing (angular) measurements, which gives the robot the ability for navigating in unknown environments, and iii) a high-level motion control system which generates online trajectories. The high-level motion control system (MCS), which represents the main contribution of this work, is inspired by the behavior-based control strategies. The MCS takes as input a very high level mission target (e.g. 'explore as much as you can') and generates online trajectories according to the mission, but at the same time minimizing uncertainty in the estimations in order to maintain the integrity of the robot. The proposed architecture is explained for simplified 3DOF dynamics, but it could be extended in a straightforward manner in order to be applied to full dynamics. Several simulations are included in order to show the performance of the proposed scheme.

There are documented evidence of micronutrient deficiency among the population of Mexico. To evaluate the nutritional status and micronutrient deficiencies in the diet of adolescents. The sample consisted of 307 adolescents. We analyzed the body composition by using anthropometric indicators. To determine the intake of micronutrients, the 24 hours reminder and software Mexfoods were used. The percentages that indicate adequate intake were classified according to the following breakpoints: Below minimum requirements, when intake was <50%; minimum requirements covered ? 50% and <75%; and exceed minimum requirements when it was ? 75 %. The BMI indicated that 21.8% of students of both sexes showed malnutrition and the prevalence of overweight and obesity was 27.9%. The micronutrient intake results indicated significant deficiencies in iron (p = 0.002), zinc (p = 0.000) and calcium (p = 0.002). The B-complex vitamins were those that had lower failure rates. We identified that the diet of adolescents has significant micronutrient deficiencies and that adolescent girls resulted with the major deficiencies.

Dendritic spines mediate excitatory neurotransmission and they can isolate the electrical activity generated by synaptic impulses, enabling them to translate excitatory afferent information via several types of plastic changes, including neoformation, disappearance, redistribution and changes in geometric shape. The fine line between normal and abnormal excitatory neurotransmission is mediated by the concerted action of glutamate-mediated stimulation and calcium ion entry into spines. Moreover, within the range of normal excitatory activity, dendritic spines undergo specific plastic changes to regulate different forms of afferent information that are often related to distinct modes of cognition-related electrophysiological stimulation, such as long-term potentiation or long-term depression.
