Resumen
La neuroestimulación puede mejorar el altruismo al aumentar la coherencia frontal-parietal del cerebro. Este enfoque dirigido aumenta el costoso reparto de recursos, particularmente en situaciones de desigualdad desventajosa, al fortalecer otras preocupaciones relacionadas.
Área de la Ciencia:
- La neurociencia es la neurociencia.
- Psicología social Psicología social.
- La economía del comportamiento es la economía del comportamiento.
Sus antecedentes:
- El altruismo es crucial para la función social, pero varía significativamente entre los individuos y las situaciones.
- Comprender los fundamentos neurobiológicos de esta variabilidad es clave para desarrollar intervenciones.
- Estudios previos de electroencefalografía (EEG) relacionaron las elecciones altruistas con la coherencia de la banda gamma frontal-parietal.
Objetivo del estudio:
- Investigar el papel causal de la coherencia oscilatoria frontal-parietal en el altruismo.
- Para determinar si la mejora de esta coherencia a través de la neuroestimulación puede aumentar el comportamiento altruista.
- Explorar el impacto de tales intervenciones en los procesos de toma de decisiones.
Principales métodos:
- Utilizó estimulación transcraneal de corriente alterna (tACS) para mejorar la coherencia de la banda gamma fronto-parietal.
- Evaluar los cambios en el comportamiento altruista, específicamente durante la desigualdad desfavorable.
- Modelado computacional empleado para analizar los efectos de tACS en las ponderaciones de la toma de decisiones.
Principales resultados:
- El protocolo tACS mejoró con éxito la coherencia fronto-parietal como se pretendía.
- Esta mejora condujo a un aumento significativo del comportamiento altruista, particularmente bajo la desigualdad desfavorable.
- El modelado computacional indicó que la neuroestimulación aumentó el peso dado a otras preocupaciones relacionadas.
Conclusiones:
- El altruismo puede ser causalmente mejorado a través de la neuroestimulación dirigida a la sincronización oscilatoria fronto-parietal.
- Este estudio establece una base neuronal para el altruismo e identifica un objetivo neuronal específico para las intervenciones.
- Los hallazgos sugieren el potencial de la neuroestimulación para mejorar el comportamiento prosocial.

02:35Band Theory
17.3K
When two or more atoms come together to form a molecule, their atomic orbitals combine and molecular orbitals of distinct energies result. In a solid, there are a large number of atoms, and therefore a large number of atomic orbitals that may be combined into molecular orbitals. These groups of molecular orbitals are so closely placed together to form continuous regions of energies, known as the bands.
The energy difference between these bands is known as the band gap.

01:21G-protein Coupled Receptors
132.2K
G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

01:01Energy Bands in Solids
2.0K
Isolated atoms have discrete energy levels that are well described by the Bohr model. And, it quantifies the energy of an electron in a hydrogen atom as En. Higher quantum numbers 'n' yield less negative, closer electron energy levels.
Band Formation:
When atoms are brought close together, as in a solid, these discrete energy levels begin to split due to the overlap of electron orbitals from adjacent atoms. This split occurs because of the Pauli exclusion principle, which states...

5.8K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

02:39Phase Diagrams
50.4K
A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). Regions or areas labeled solid, liquid, and gas represent single phases, while lines or curves represent...

01:20Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)
1.7K
Two NMR-active nuclei bonded to a central atom can be involved in geminal or two-bond coupling. Geminal coupling is commonly seen between diastereotopic protons in chiral molecules and unsymmetrical alkenes, among others.
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...
