recording electrical activity from identified neurons in the intact brain of transgenic fish

Karmaşık davranışlar düzenleyen nöral devrelerin hücre fizyolojisi anlayışı bu iş CNS sinir devresi bozulmadan kalır sağlam bir beyin hazırlanmasında yapılabilir hangi model sistemler kullanılarak büyük ölçüde geliştirilmiştir. Biz gonadotropin salgılatıcı hormon (GnRH) nöronlar genetik sağlam beyinde tanımlanması için yeşil flüoresan protein ile etiketlenmiş edildiği transgenik balık kullanabilirsiniz. Balık GnRH nöron birden fazla nüfusa sahip ve işlevleri onların beyindeki yeri ve 1 ifade ettiği GnRH gen bağlıdır. Biz transgenik Medaka balık bozulmamış beyin (Şekil 1B ve C) kullanarak koku ampuller ile ilişkili terminal sinirler (TN) bulunan GnRH3 nöronlar bizim gösteri odaklanmıştır. Çalışmalar Medaka TN-GnRH3 nöronlar merkezi sinir sistemi ile dış çevreden bir bilgi verici olarak hareket eden, nöromodülatör olduğunu göstermektedir; they gibi tanınmış hipotalamik GnRH1 nöronlar 2, 3 yapmak. TN-GnRH3 nöronların spontan aksiyon potansiyeli ateşleme tonik desen içsel bir özellik 4-6, frekans, hipofiz-gonadal fonksiyonları düzenleyen doğrudan bir rol oynamaz hangi conspecifics 2 ve nöropeptid kisspeptin 1 5 ila görsel ipuçları ile modüle edilir. Bu video, TN-GnRH3 nöronların nasıl nöronlar belirlemek ve tüm beyin kendi elektriksel aktivite izlemek için size göstermek için gelişmiş yeşil flüoresan protein 7 bağlantılı Gnrh3 promotor bölgesinde içeren bir transgen ifade edildiği transgenik Medaka istikrarlı bir satırını kullanın Hazırlık 6.

Medaka balık Kesilerek çıkarılan beynin GFP-etiketli TN-GnRH3 nöronların ikili kümelerinin bir örneği Şekiller 1B ve 1C &#39;de gösterilmiştir. Her küme 8-10 GnRH nöronları içerir. Hedef TN-GnRH3 kendiliğinden nöronal aktiviteleri 0.5-6 Hz tipik ateş oranları ile akım kelepçe modu (I = 0) kaydedildi. Aksiyon potansiyeli ateşleme paterni oldukça düzenli interspike aralığı ile, tipik bir tonik veya dayak kalıptır. Örnek izleri Şekil 2 (:;: ...
