Association Areas of the Cortex01:21

Association Areas of the Cortex

6.2K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Protein Families02:47

Protein Families

15.7K
Protein families are groups of homologous proteins; that is, they have similarities in amino acid sequences and three-dimensional structures. Protein families usually occur because of gene duplication, where an additional copy of a gene is inserted into the genome of an organism.   Mutations that change the amino acids but still allow the protein to be properly synthesized, will lead to new protein family members.   If these new proteins contain similar amino acids in key...

Assessment of apical radial pulse01:25

Assessment of apical radial pulse

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Fixed Action Patterns01:06

Fixed Action Patterns

16.5K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Atomic Force Microscopy01:08

Atomic Force Microscopy

3.6K
Atomic force microscopy (AFM) is a type of scanning probe microscopy that can analyze topographic details of various specimens like ceramics, glass, polymers, and biological samples. AFM offers over 1000 times more resolution than the optical imaging system. Images generated from AFM are three-dimensional surface profiles, offering an advantage over the flat, two-dimensional images from other imaging techniques.
The AFM Probe
The probe is regarded as the heart of any AFM setup and comprises the...

Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

6.1K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Área de la Ciencia:

  • Biología del comportamiento
  • Psicología evolutiva
  • Ciencias cognitivas
  • Primatología

Sus antecedentes:

  • La investigación de la percepción facial a menudo se basa en rostros humanos, lo que limita los estudios sobre mecanismos evolutivos y cognitivos más amplios.
  • Existe la necesidad de estímulos que son similares a los humanos pero claramente no humanos para explorar las atribuciones sociales y la percepción más allá de la variación humana actual.

Objetivo del estudio:

  • Para introducir la base de datos de caras de simios, un nuevo estímulo para la investigación en biología del comportamiento y psicología evolutiva.
  • Proporcionar un recurso versátil para investigar la percepción facial, la cognición social y la psicología evolutiva utilizando imágenes faciales artificiales y generalizadas de homínidos.

Principales métodos:

  • La base de datos comprende 620 imágenes faciales fotorrealistas generadas artificialmente de 31 modelos de homínidos generalizados.
  • Las imágenes presentan múltiples variantes de coloración ocular y se emparejan con datos morfométricos geométricos y calificaciones perceptivas (Amenaza, sociabilidad, confiabilidad, salud, edad, masculinidad).
  • Los archivos .psd editables permiten la generación de diversos fenotipos de ojos de mono.

Principales resultados:

  • El conjunto de datos presenta un diseño único "humano pero no humano", que facilita la investigación sobre la percepción facial.
  • Los estímulos son morfológicamente diversos, lo suficientemente humanos como para provocar atribuciones sociales, pero claramente no humanos.
  • La información de normalización incluye calificaciones perceptivas en las construcciones sociales clave.

Conclusiones:

  • La base de datos de caras de simios es un recurso valioso y versátil para estudiar la percepción facial y la cognición social en humanos y primates no humanos.
  • Este nuevo conjunto de datos abre nuevas vías para la investigación de los mecanismos cognitivos y perceptivos subyacentes a las atribuciones sociales.
  • Facilita la investigación que explora los límites de la percepción facial más allá de la variación humana existente.
