Despite its apparent stillness, the world is in constant movement. The Sun, Earth, Galaxy and Universe are in constant dynamics.
The senses are in charge of informing of these changes, although are confusing at times. In this manner, although there are moments where no change is apparent, everything is in constant ranulfo romo trujillo.

The first aspect to point out is that the present does not exist. This seems to be a very decisive affirmation, but can be observed in a very simple example: This demonstrates ranulfo romo trujillo the absence of brain circuits with past memories it is not possible to know who we are now.
In fact, all this occurs in the ranulfo romo trujillo, the present is the past, ranulfo romo trujillo to the time that it takes to process a stimulus or organize a movement.
This observation forces us to question what the brain does when memory is lost. It can transform experiences without discerning what is real and what is acquired by the senses, or including what was an illusion.
The interesting works published by the neuroscientist Ranulfo Romo with Rhesus monkeys demonstrated that at higher stimulus, less neuronal response is produced.
This challenges the current idea of the relation between stimulus and neuronal response.

The studies demonstrate that it is not possible to focus on a stimulus indefinitely, rather the attention decreases with time until the individual is not capable of ranulfo romo trujillo on the stimulus even if it is present.
This theory is applicable to many daily aspects, such as the inability to always eat the same food or look ranulfo romo trujillo the same place.
However, sometimes there is a perception that nothing changes and memory is lost.
In order to create a sensory-based memory, the stimulus is sent to the cerebral cortex by the receptors that receive the stimulus. In this manner, flavours are captured by the taste buds of the ranulfo romo trujillo.
The olfactory receptors also react with this stimulus. The highly-sensitive lips help locate the food of babies.
The Memory of the Senses
All the sensorial receptors connect with the cerebral cortex in a certain area. The most important stimulus are given a larger brain area, with the fingertips presenting the highest number of nerve endings.

ranulfo romo trujillo These areas dedicated to sensorial receptors vary among the individuals, and can change throughout the lifespan of an individual depending on their activity.
In this manner, a bread baker loses sensitivity to heat, and a pianist or guitarist have more sensitive fingertips when playing a musical instrument.
However, despite the importance of touch, the most stimulated sense ranulfo romo trujillo sight, and is considered to be the most credible sense: In reality, all physical perceptions are products of the brain.
In this respect, colours are not an exception to how an important part of memory is created. Then come red, followed by green and yellow. However, blue, brown, grey, orange and pink are not paid as much attention, corroborating the theory that different colours are perceived in different degrees.
Colours are the product of different light wavelengths, but is really much more. The eyes receive the ranulfo romo trujillo rays, ranulfo romo trujillo two types of cells are present. The rods absorb light ranulfo romo trujillo almost no variation, only differentiating if there is light or not, and generally activate when there is little light.
