Enzimas y catálisis Las enzimas son proteínas que actúan como catalizadores en reacciones químicas específicas en el cuerpo humano. Estas moléculas aceleran las reacciones químicas al disminuir la energía de activación necesaria para que se produzcan. Sin las enzimas, muchas reacciones químicas importantes en el cuerpo humano tendrían lugar demasiado lentamente para mantener la vida….
¿Qué es la bioquímica? La bioquímica es una disciplina científica que estudia los procesos químicos que ocurren en los seres vivos. Es una rama de la biología que se enfoca en la química de la vida, y es fundamental para entender cómo funcionan los organismos a nivel molecular. La bioquímica es importante en la ciencia…
Neurotransmitters and Sleep Sleep is a vital component of overall health and well-being, and neurotransmitters play a crucial role in regulating sleep patterns. Two key neurotransmitters involved in sleep are serotonin and melatonin. Serotonin helps to regulate the sleep-wake cycle, while melatonin is responsible for inducing sleepiness at night. Imbalances in these neurotransmitters can lead…
The Ethics of Neurotransmitter Manipulation The use of neurotransmitter manipulation for therapeutic purposes raises important ethical considerations. On one hand, these interventions have the potential to greatly improve the lives of individuals struggling with mental health disorders. By targeting specific neurotransmitter systems, healthcare professionals can help restore balance and alleviate symptoms such as anxiety and…
Symptoms of Neurotransmitter Imbalances Imbalances in neurotransmitter levels can lead to a variety of symptoms that can significantly impact an individual’s quality of life. One of the most common symptoms is anxiety, which can manifest as persistent worry, fear, and panic attacks. Anxiety disorders are often associated with imbalances in neurotransmitters such as serotonin, GABA,…
Glutamate: The Excitatory Neurotransmitter Glutamate is one of the most abundant neurotransmitters in the brain, and it plays a crucial role in promoting neural activity. When glutamate binds to receptors on neurons, it causes an influx of calcium ions, which triggers the release of even more glutamate. This creates a positive feedback loop that can…
Serotonin: The Mood Regulator Serotonin is a neurotransmitter that plays a crucial role in regulating mood, sleep, and appetite. It is often referred to as the ‘feel-good’ neurotransmitter because of its ability to promote feelings of happiness and well-being. Low levels of serotonin have been linked to depression, anxiety, and other mood disorders. In fact,…
What are Neurotransmitters? Neurotransmitters are chemical messengers that play a crucial role in communication between neurons in the brain and nervous system. These tiny molecules are responsible for transmitting signals across synapses, allowing us to think, feel, move, and experience the world around us. The Role of Neurotransmitters in the Brain Neurotransmitters are chemical messengers…
Transtorno neurológicos são condições que afetam o funcionamento do sistema nervoso, composto pelo cérebro, medula espinhal e nervos. Esses transtornos podem causar sintomas variados, como alterações na sensibilidade, na motricidade, na visão, na audição, na fala, na memória e no comportamento. Existem muitos tipos de transtorno neurológicos, que podem ter origens diferentes, como genéticas, infecciosas,…
Cognição e processamento são dois conceitos fundamentais para entender como o cérebro humano funciona. A cognição é a capacidade de adquirir, armazenar, manipular e usar informações de diferentes fontes e modalidades. O processamento é como essas informações são organizadas, integradas e transformadas em conhecimento e ação. A cognição envolve processos como atenção, percepção, memória, raciocínio,…
