Dr. Rodrigo Herrera-Molina

Mecanismos moleculares y celulares esenciales para el aprendizaje, la memoria y el recuerdo.

Alteraciones moleculares conducentes a cambios en circuitos neuronales en el cerebro de pacientes y ratones trangenicos.

¿Cómo se forma y cómo mantiene la memoria? ¿Es posible recuperar memorias perdidas?. En particular, el Dr. Herrera-Molina estudia como la proteína transmembrana Neuroplastina, que se encuentra en las sinapsis y en todas las neuronas en los cerebros de mamíferos adultos, controla la presencia de la bomba de calcio PMCA (Plasma Membrane Calcium ATPase) y su interacción funcional con receptores para glutamato lo que es esencial para la correcta generación y terminación de señales de calcio en neuronas del cerebro. La deficiencia o mutaciónes en Neuroplastina lleva a graves problemas cognitivos en pacientes infantes y altera el aprendizaje y la memoria en ratones.

Desarrollo de electrodos cerebrales y su modificación con nanomateriales.

¿Cómo registrar la actividad de neuronas únicas en un cerebro mínimamente invadido? ¿y de manera individualizada, estable, de bajo costo? El Dr. Herrera-Molina forma parte de un grupo internacional e interdiciplinario, compuesto por médicos, ingenieros, y veterinarios trabajando en Japón, Alemania y en los Estados Unidos, que se enfoca en la fabricación de nuevos dispositivos para realizar registros electrofisiológicos en cerebros de distintas especies de animales experimentales.
